Phineas and Ferb The Movie: Across the 2nd Dimension is a Disney Channel Original Movie based on Phineas and Ferb, originally aired on August 5, 2011. It was first announced by Jeff “Swampy” Marsh during January 2010 interview with the Daily Telegraph.
The film was released in cinemas in Spain, making it the sixth movie based on a Disney animated television series to be released in theaters (the previous ones being DuckTales the Movie: Treasure of the Lost Lamp, A Goofy Movie, Doug's 1st Movie, Recess: School's Out, and Teacher’s Pet). It was also supposed to be in theaters in Belgium and the Netherlands, but was canceled and premiered on their Disney Channels November 25, 2011.
Phineas, Ferb, Perry, Candace, and Dr. Doofenshmirtz, who were all captured by the 2nd Dimension Doofenshmirtz, are about to be fed to a Goozim. Phineas compares their current situation to how the day began, and states that everything started out so well that morning.
The scene switches to the beginning of the day, with Phineas and Ferb waking up due to Perry's chattering. The trio do their daily morning routine (such as get dressed, brush their teeth), while singing Everything's Better with Perry, a song about how everything is better with their pet. Afterwards, they fall down the stairs next to their parents, and reminisce about when they adopted him from the Organization Without a Cool Acronym's animal shelter. Subsequently, they play baseball, launching the balls off of Perry's tail. They then decide to play platypus badminton using two giant platypus-shaped catapults, which are able to launch objects off their tails like real platypuses.
With the help of their friends Isabella, Buford and Baljeet, they construct them, launch themselves off of the tail of the platypult in a large shuttlecock, and fly through the air. Perry, who has assumed his secret agent role as Agent P, has returned from a mission briefing with Major Monogram and Carl; the latter who has given him several new gadgets.
While riding in his new rocket car, Agent P collides with Phineas and Ferb’s shuttlecock that changes its course and crashes on the roof of the Doofenshmirtz Evil Incorporated headquarters, destroying Dr. Doofenshmirtz’s latest invention, the Other-Dimension-Inator.
Meanwhile, after learning that her boyfriend, Jeremy, is looking for colleges, Candace decides to grow up and act more like an adult. She and her friend Stacy go to the backyard to bust the boys, since, now that Candace is an “adult”, she can bust the boys herself. However, she finds that her brothers and the platy-pult are gone, with only Isabella and Baljeet remaining. Candace concludes that the "Mysterious Force", the force that she believes takes away Phineas and Ferb’s invention before her mother can see them, recognizes Candace as an adult, and so kept her from seeing the boys' invention as well. She and the rest of the group go to the park to look for the boys.
Feeling sorry for him, and not knowing that he is evil, Phineas and Ferb help Dr. Doofenshmirtz rebuild his Other Dimension-inator, much to the horror of Perry, who must pretend to be a mindless pet in the vicinity of his owners lest they find out his secret. He tries to stop them by taking away Phineas's wrench and peeing on Doofenshmirtz's couch, but to no avail.
They successfully open a portal to the 2nd Dimension and step through it. They find that that the Tri-State Area in this dimension has been taken over by the 2nd Dimension Doofenshmirtz, who has a scar that goes over his eye-patch. Dr. Doofenshmirtz is redirected by the 2nd Dimension Monogram to a ride that takes him straight to Doofenshmirtz-2. There, they meet, and perform a duet.
Phineas, Ferb, and Perry follow, and Doofenshmirtz-2 recognizes their pet as Perry the Platypus, while the regular Doofenshmirtz doesn’t. Doofenshmirtz-2 sends his minion, General Platyborg, the 2nd Dimension Perry who was defeated and turned into an evil cyborg by Doofenshmirtz-2 a long time ago, to attack Perry, hoping that it will cause Perry to reveal that he is a secret agent. However, Perry remains in his mindless guise even after being hit. Doofenshmirtz-2 then tells Platyborg to hit the boys, to which Perry punches the Platyborg away and reveals his identity.
Phineas and Ferb are surprised at this, and hurt that Perry didn't tell them that he was an agent (primarily Phineas, who yells at him). Doofenshmirtz-2 summons his Norm Bots to seize the trio. The three fall through a window, but Agent P releases his parachute. They land on top of another building, where Agent P does combat against Platyborg with his feet stuck in a skull from an animal skeleton from Doofenshmirtz-2’s lair. Phineas and Ferb trap Platyborg in Agent P’s parachute.
Phineas begins to express his anger again until he realizes that Perry is caught in the parachute. Phineas and Ferb try to pull him back up, but fall; fortunately they all end up being "saved by unconventional architecture". A Norm Bot approaches them as well as Platyborg, but the Norm Bot is hit by the skull and Platyborg is hit by a bus. Phineas, Ferb and Perry are then able to escape.
Back in Danville, Candace, Stacy, Isabella, and Baljeet have found Buford in the park chewing Victory Gum, as he assumed he had won the platypus badminton game they were playing earlier, even though it was more of a forfeited win since Phineas and Ferb had gone missing. Candace and Stacy decides to go back to the Flynn-Fletcher backyard while Isabella, Baljeet and Buford stay in the park.
In the 2nd Dimension, Phineas expresses his anger again about Perry being a secret agent while Ferb reminds him to try to use a remote version of the Other Dimension-inator to get home, but it just opens a portal to another dimension they don’t know. Doofenshmirtz-2 tells Doofenshmirtz that what had caused him to go more evil than him and take over the 2nd Dimension Tri-State Area was that he had lost his toy train when he was a child, and Doofenshmirtz is unable to believe that that was his emotionally scarring back-story while he had so many more of those than him. Meanwhile, Phineas is trying to get over the fact Perry is a secret agent and wonders simultaneously if Perry is family. Ferb assuages him, and the boys decide they to need find their 2nd Dimension selves, who have never heard of summer before and are successful in explaining summer to their counterparts. Agent P, upon seeing a news report on TV saying that he should turn himself in to Doofenshmirtz-2 or else Doofenshmirtz-2 will hurt his friends, begins to leave, but is stopped by Phineas and Ferb.
Phineas disowns Perry, telling him to go ahead and leave, as he can’t trust Perry anymore, and Agent P leaves. Afterwards, they attempt to go across the street to the 2nd Dimension Isabella’s house, but are stopped by a lone Norm Bot, who is taken down by the 2nd Dimension Buford. It is revealed that Buford-2 was part of the The Resistance against Doofenshmirtz-2, but became so good at it that he started resisting the Resistance too. The five fall down a chute once entering Isabella’s yard, and end up being tied by the Firestorm Girls, the 2nd Dimension versions of the Fireside Girls. They are interrogated by the 2nd Dimension Isabella, to which Phineas replies that they are Candace’s brothers. They are untied and led to 2nd Dimension Baljeet, who prefers to be called “Dr. Baljeet.” He explains that the 1st Dimension and the 2nd Dimension are right next to each other, but to get to the 1st Dimension, they would need a lot of energy as they would be going against the flow of energy between the multiverses. Their other option would be to go around clockwise, but it is unknown to how many dimensions they have to go through to end up in their own. They are later introduced to the leader of the Resistance, 2nd Dimension Candace, who shows up and commands everyone to begin work to divert energy to bring Phineas and Ferb back to their dimension.
Meanwhile, Doofenshmirtz-2 has decided to go the 1st Dimension’s Tri-State Area to conquer it. He gets regular Doofenshmirtz to create another Other Dimension-inator, but it fails to work as it seems they will need the boys’ help to make it. Dr. Baljeet has been able to open a portal to the 1st Dimension. Upon seeing a news report that Perry has been captured, Phineas and Ferb want to rescue him. Meanwhile, Candace and Stacy are in the Flynn-Fletcher backyard, and Candace tries to talk to the Mysterious Force. The portal from the 2nd Dimension opens up, which the two girls believe is the Mysterious Force. Candace goes through, causing the portal to close, and her being stuck with the 2nd Dimension gang.
Phineas, Ferb, Candace, Candace-2, Buford-2, Isabella-2, along with Phineas-2 and Ferb-2, who have stowed away, go underground in mine carts to attempt to break into Doofenshmirtz-2’s lair to rescue Perry. But they find out that it is a trap, and they are surrounded.
Doofenshmirtz-2 taunts Perry that he has captured him and his friends around 3:30 to 4 pm EST. Perry remembers something, and presses a button on his watch, which opens up a hologram of Major Monogram, who, at that moment, is in the shower. The Doofenshmirtzes, Platyborg and the Norm Bots look away in disgust, and the kids are able to escape. The group tries to race away in the mine carts as the Norm Bots pursue them. To save her and her brothers, Candace-2 separates the mine carts, and she and the rest of the Resistance are able to escape, while Phineas, Ferb, Candace, and Agent P are captured.
Back in Danville, Stacy builds a shrine to the Mysterious Force as an apology for not believing in it, in hopes that it will bring her friends back. Meanwhile, Phineas and Ferb refuse to fix the Other Dimension-inator, but Doofenshmirtz remembers the boys removed his self-destruct button, repairing the device. Now obsolete, Doofenshmirtz-2 sentences the four to doom, as well as regular Doofenshmirtz, as he had gotten on Doofenshmirtz-2’s nerves. The group, in chains, is led to a caged Goozim surrounded by lava. Perry is able to get keys to unchain the gang, but the Goozim’s movements toss them around, and the keys drop near the lava that takes up the ground. As the gang nearly dangles near the magma (thanks to Doofenshmirtz's poor climbing skills), Candace is able to catch the keys. Suddenly, Candace-2 shows up with the Other Dimension-inator remote. She defeats the surrounding Norm Bots, and throws it to Phineas. When he realizes what it is, he tells Perry to let go of the Goozim's cage, but he hesitates. Phineas pleads with Perry to trust him, and he lets go of the cage, just as Phineas opens a portal to another dimension. The group falls through a portal to a flower dimension, and they use the keys to unchain themselves.
The portal is still open, however, so the Norm Bots come through it, so Phineas closes the portal. Candace-2 is captured, and Doofenshmirtz-2, though enraged, goes on with the invasion of the 1st Dimension Tri-State Area. The group goes through numerous dimensions with the Norm Bots in pursuit.
As Buford, Baljeet and Isabella are talking in the park, Phineas, Ferb, Candace, Perry and Doofenshmirtz manage to get back in the 1st Dimension. At the same time, however, Doofenshmirtz-2 arrives at Doofenshmirtz Evil Incorporated, retracts the roof as the Other Dimension-inator rises up and activates a portal, allowing millions of Norm-Bots to invade Danville. Candace-2, who has been imprisoned, is rescued by the 2nd Dimension Jeremy, and Phineas-2 and Ferb-2, who have taken on new clothing. After hugging her brothers, Candace tells the 3 of them to go with her to help stop Doofenshmirtz-2 from taking over the 1st Dimension, and they all leave.
Agent P is told by Major Monogram to assist the other agents in fighting the invading robots, while Phineas, Ferb, and Candace are simply told to go home. There, Perry’s locket, which Phineas has, beeps, leading them to Agent P’s lair. They receive a message, activated by the locket, saying that, the Tri-State Area is in an emergency level Alpha Red. Agent P thus needs their help, and that he knows they can help him because of their Big Ideas. Many of Phineas and Ferb’s inventions from past episodes of the series are replicated, and the kids from Danville take control of them, managing to save the agents, who were surrounded by the Norm Bots, and go to war with the Norm Bots. In the heat of battle, Phineas and Perry get to the top of Doofenshmirtz Evil Incorporated building, where they find Doofenshmirtz-2 sending off more of his robots. Perry fights Platyborg, while Phineas goes head-to-head with Doofenshmirtz-2, after he is caught trying to disable the portal.
Perry is eventually able to defeat Platyborg, who, with a chicken stuck on his head and corn in his hands, gets his tail stuck in an electrical socket and is electrocuted. Phineas realizes the dish is what controls the robots, so he goes for the baseball launcher, which Doofenshmirtz-2 grabs and is subsequently cornered by Doofenshmirtz-2, who aims at him with the baseball launcher. Perry hands Phineas a baseball bat, which he uses to hit the baseball that Doofenshmirtz-2 shoots at him from the launcher. The baseball hits the satellite which controls the Norm Bots, and they all fall to the ground, deactivated. Ferb, who has been climbing up the side of the building with plungers, reaches his brother and pet. An enraged Doofenshmirtz-2 emerges from the ground in the cockpit (sleeve) of a giant robot version of himself and goes to smash Phineas, Ferb, and Perry.
At that moment, Doofenshmirtz, who left his keys in the 2nd Dimension and has been trying to get his neighbor Mrs. Thompson to let him into the building, shows up, and unveils his toy train from his childhood, Choo-Choo. Once he sees his lost train, Doofenshmirtz-2 climbs down the robot, and embraces the toy.
Meanwhile, Candace, who has given up on becoming an adult, goes to the movie theater, where her parents Linda and Lawrence, have been. She tries to get her mom to go outside with her to see the grand battle that is going on in hopes that the mysterious force will make it disappear. Doofenshmirtz-2, who has now become less evil, apologizes for his wrongdoings, and reveals that he has had Self-Destruct buttons on his Norm Bots after all. He presses a button on a remote, and all the robots in the Tri-State Area blow up and disappear. Candace and Linda get outside, and find that all the robots have vanished, and that Candace has failed at busting her brothers – again, something she takes pride in.
Doofenshmirtz-2 returns to the 2nd Dimension, where he is arrested by Monogram-2 and the Firestorm Girls. The Resistance enters Danville, and thanks Phineas, Ferb, and Candace for all they’ve done. The Platyborg has had the evil “fried” out of him, and Phineas-2 and Ferb-2 rush to hug him, happy that their pet has returned. After the 2nd Dimension characters leave, Monogram and Carl show up, and tell Phineas and Ferb that Perry has to go away forever due to his secret being blown. The boys ask if there’s something else they can do to keep their pet, and Monogram and Carl remember that Doofenshmirtz built an Amnesia-inator, and that everyone agreed to have their memory of that whole day (including learning Perry’s identity as Agent P) so they can keep him.
Back at the O.W.C.A.’s headquarters, Phineas, Ferb, Candace, Jeremy, Buford, Isabella, Baljeet and others are lined up (Doofenshmirtz tied up for some reason) to get their memories erased. The brothers say their last good-byes to Agent P. As everyone got ready to get their memories erased by the Amnesia-inator, Isabella confirms with Monogram that no one will remember anything from today, then proceeding to kiss Phineas. Phineas was surprised and seemingly somewhat pleased at this, Isabella tells Carl fire the Amnesia-inator and Phineas yells "Wait! Wait! Wait!", but to no avail. Later, Agent P enters his lair, and plugs his camera into the screen, and watches a slideshow of photos taken by he and his owners during their adventure. He smiles and saves the pictures.

Lawrence: OK, boys, you can pick out any pet you like.
Linda: (picks up and holds Young Phineas in order to see the kitten) Hey, look, Phineas. This one's looking at you!
(while playing Platypult-baseball)
Phineas: Oh, yes, sports fans, that may be the best hit ever in the history of platypult baseball! And the crowd exhales loudly through their mouths! (breathes loudly)
Stacy: The irony is, that as a grown up, you don't NEED to tell your mom. You can just bust them yourself.
Candace: (gasps) That's it! Stacy, I'm old enough to bust them myself!
Phineas: Oh, there you are, Perry.
Dr. Doofenshmirtz: Perry?
Dr. Doofenshmirtz: You know, I can't help but notice that your scar goes over your eye patch.
Dr. Doofenshmirtz (2nd Dimension): Yeah?
Dr. Doofenshmirtz: Wait a minute. I'm confused. Why does their platypus fight so good?
(Perry puts on his fedora)
Phineas: I'm Phineas and this is my brother Ferb.
Doofenshmirtz: I'm Dr. Heinz Doofenshmirtz, but my friends call me... (pause) I just got into such a funk.
Ferb: Well he did pee on the couch.
Dr. Doofensmirtz: Wait a sec, I just realized something! That was a conscious choice! You peed on my couch!
Dr. Doofenshmirtz (2nd Dimension): Guards?
Perry pushes the brain freeze remote.
Phineas: I'm–I'm sorry. I'm just having trouble processing this right now.
(Perry gives him a pamphlet.)
Phineas: Oh for crying out loud! (walks over to help Perry out of the skull) What, they didn't teach you how to get out of this in spy school?!
Phineas: Look, there's a logo on this parachute. He's got his own logo?
Both Doofensmirtzes: Curse you, Perry the Platypus!
Dr. Doofensmirtz: Jinx, you owe me a soda.
Normbot: (with a buffalo skull on his head) Get me! I'm a Georgia O'Keeffe painting!
Cab driver: Fourth and Main! (the Platyborg gets off and gives the cab driver some money) What, no tip? (the Platyborg takes out a weapon) Never mind, I'm good. (drives away)
Phineas: (After he says "you're a secret agent!? the second time) Anyone else here living a bizarre double life? (Ferb raises his hand) Put your hand down, Ferb. (Ferb lowers his hand)
Dr. Doofenshmirtz-2 shows Dr. Doofenshmirtz a picture of Perry without his hat.
Dr. Doofenshmirtz (2nd Dimension): Now tell me, other-dimension me, what do you see here?
Dr. Doofenshmirtz (2nd Dimension): When I was a small boy in Gimmelshtump, I had a toy train named Choo-Choo. Then, one day, I lost it.
Young Doofenshmirtz (2nd dimension): Choo-Choo?
Dr. Doofenshmirtz (2nd Dimension): Since you have neglected to take over your Tri-State Area, I think I go over there and go it a shot myself.
Dr. Doofenshmirtz: Great, we can be a team!
Candace (2nd Dimension): Are there four of you in this room?
Phineas: Five counting Perry.
Candace (2nd Dimension): Then we've got work to do, Isabella, start redirecting the power.
Isabella (2nd Dimension): Aye, aye!
Dr. Doofenshmirtz: Stand back in awe!
Inator shorts out (Because it's wired incorrectly)
Both Doofenshmirtzes: Ah, Perry the Platypus.
Dr. Doofenshmirtz: Jinx, now you owe me two sodas.
Candace: Why is Isabella suddenly fashionable?
Isabella (2nd Dimension): What do you mean suddenly?!
Candace sees her 2nd Dimension self
Candace: Hey, is that me? I look good!
Buford (2nd Dimension): I don't remember it being so dark down here.
Candace (2nd Dimension): Dark?
Phineas: Perry! W-We came to rescue you.
The camera zooms out, showing Norm Bots surrounding them.
Seeing 2nd Dimension Candace fight the Norm bots
Phineas: Can you do that?
Buford (2nd Dimension): (Looking at 2nd Dimension Candace) I am so in love with her right now.
Isabella (2nd Dimension): What?
Seeing Phineas and Ferb blasting the Norm bots with one of its arm
Phineas (2nd Dimension): Can we do that?
Dr. Doofensmirtz (2nd Dimension): There, you're trapped. Now, you have no choice, but to fix my machine!
Dr. Doofensmirtz (2nd Dimension): Yes, yes everyone. Doom, doom, doom and-
Both Doofensmirtzes: Doom!
Dr. Doofenshmirtz: Oh you caught it! Here, unlock me.
Candace: Are you even paying attention!
Stacy: (to the mysterious force) Oh you can see I'm really trying so please bring back Candace!
Candace walks up behind her
Computer: Welcome, Phineas and Ferb. Please insert the key.
Phineas: (to Ferb) Do you have a key?
Dr. Doofensmirtz (2nd Dimension): (to Phineas, as he is about to fire him with the baseball launcher) You know, all that's going to happen from you guys coming up here is that I'm going to have a brand new Platyborg. And maybe even a Boyborg! Huh? Try saying that five times fast! Boyborg, boyborg, boyborg, boyborg, boyborg...eh. I guess it's not that hard to say. Never mind.
Dr. Doofensmirtz (2nd Dimension): (to Phineas, Ferb, and Perry, after he emerges with a giant robot version of himself) Now, tremble before me! No, I'm down here. See? One last trick up my sleeve. It's me! I'm the trick up my...own sleeve, cause I'm...I'm in the sleeve. Get it? (sighs) Pearls before swine. (prepares to attack the trio) Hope you've got your 3D glasses, cause I'm coming at you!
(The bots outside the theater explode. A second later, Candace drags Linda out.)
Candace: Come on, come on. Hurry!
Phineas: Wow, imagine the fun we can have, now that we now you're a secret agent!
Major Monogram: Yes, yes, the next 15 minutes should be a real hoot. Of course, then Agent P will be sent away forever!
Isabella: Uh, Major Monogram?
Major Monogram: Uh, Yes?
Dr. Doofenshmirtz: Behold, the Otherdimensionator! (laughs manically)
Norm: Sir. I finished setting up the buffet.
Vanessa (2nd Dimension): Dad, did you outlaw Tony Marzulo? (Doofenshmirtz-1 rises from his seat) If you keep banishing every boy who takes an interest in me, I'll never have a social life.
Dr. Doofenshmirtz (2nd Dimension): Done and done.
Jeremy: What happened? Wh-Where are we?
Phineas: Hey, why is Perry wearing a hat?
I know what we're gonna do today
Phineas: Ferb, I think I know what we're gonna do today.
Phineas: Ferb, I know what we're gonna do today! We're gonna save the entire Tri-State Area!
The "Too Young" Line
Phineas: (In the song Kick It Up A Notch) But we're a little young to be doin' what we're doin', yeah.
Ferb: (imitates Perry's chatter)
Phineas: (To Perry) Of course, Ferb and I knew exactly what to call you.
Young Phineas and Ferb: Bartholemew.
Phineas: (To Perry) So, not only have you been leading a double life this whole time, but you sat there and let us help an evil scientist open an evil portal into an evil dimension. And you did nothing to stop us?
Ferb: Well, he did pee on the couch.
Ferb In Summer (Where Do We Begin?): It's noticeably warmer
Phineas: You know, I used to think you couldn't spell "platypus" without "us".
Ferb: Well, you can, but it would just be "Platyp".
Ferb: Whoa. Deja-vu-ish.
Ferb: Well, we've had a lot of great days, but we only have one Perry.
Sings in Everything's Better with Perry, Summer (Where Do We Begin?) and Kick It Up A Notch.
Isabella (2nd Dimension): (Tough voice) Whatcha doin'?
Perry's entrance to his lair
A tube behind a painting, he lifts it and gets sucked in, Perry ends up being in a tube elevator and riding down to his lair, he sees and salutes Pinky, a lot of old agents are seen too. Phineas and Ferb use exactly the same entrance later in the movie, and at the last scene, Perry is seen going down the elevator.
Hey, where's Perry?
Phineas: Hey where's Perry?
Phineas: Hey, where's Perr- Oh, that's right...
Phineas: Hey, where is Dr. D?
Doofenshmirtz Evil Incorporated!, When Doofenshmirtz sees the blimp the jingle (remixed) is heard in the background, Doofenshmirtz Evil News Broadcast!, Doofenshmirtz Evil News Update!
Mistaking Doofenshmirtz for a pharmacist
Phineas: (to Perry) So this is where you disappear to everyday? You come here and fight this guy?
Doofenshmirtz: No no, he fights me, he doesn't really know this guy.
- Phineas and Ferb bought Perry in a pet store that is owned by Carl (in a girl disguise) and Major Monogram (younger).
- Despite Mysterious Force being cut from the movie, the movie still has a total of 14 songs, with 13 original ones. This makes the feature have more songs than "Rollercoaster: The Musical!"
- This is the first time Phineas and Ferb are shown tied up and chained. The second time was in "Escape from Phineas Tower."
- A DVD was released on August 23, 2011.
- If you look closely, the Resistance HQ and Pinky's HQ from Day of the Living Gelaton, Isabella and the Temple of Sap and Bee Story match up almost 100 percent, the only difference being the color scheme and a few small details on the Dashboard looking thing under the lair monitor. They are most likely the same thing since the OWCA is not around anymore in the second dimension. And since both are under Isabella's house, a resistance member probably discovered an old entrance into the lair, repainted it, and formed this as the Resistance Head Quarters
- The original title was Phineas and Ferb: Across the 2nd Dimension In Fabulous 2D, which can still be seen in the opening of the movie. The translation of this title is also still being used in Latin American trailers.
- This movie would have been be in cinemas in the Netherlands, Spain and Belgium.
- Five onlines games were created around the movie:
- Phineas and Ferb The Movie Game: The Dimension of Doooom!, was created similar to Transport-inators of Doooom!. Here, Phineas, Ferb, Perry, and the 2nd Dimension's Candace are playable characters. The full game was first seen on June 17, 2011, which had 8 (+Tutorial) levels. It may also indicate that the 2nd Dimension's Isabella has a crush on Ferb, but it is not shown that 2nd Dimension Isabella has a crush on Ferb in the movie. Given the game's status as non-canon, this is most likely untrue. The game was expanded on August 22, 2011, to a total of 12 (+Tutorial) levels, to explain that the Norm Bots were trying to take over the 1st Dimension Danville.
- 2-D Yourself is a game where the player can create a character to see Danville and Danville 2 and find downloadable stuff for the computer, was released late June 2011.
- Agent P Strikes Back, a game where Perry must help other agents get out of their traps and help Perry get to Platyborg, was created on July 1, 2011.
- Platypult Badmition, a game where the player controls a birdie with different power-ups, was created on July 29, 2011. A very similar game is also on the Toy's 'R Us website. If the player wins that game, the player can see a short clip from the movie, which is the part when Isabella, Buford, and Baljeet come into the backyard.
- Robot Riot!, a game where the player sends defenders to battle the Norm Bots, was created on August 6, 2011. This game is notable in the fact that the Fireside Girls are playable and seen for the first time (except Adyson Sweetwater) The second came in Isabella's Fireside Music Challenge, which was released January 11, 2012 on Disney.com's site, which has the aftermentioned Adyson, though only Isabella is playable for that game.
- Images for the Original Plot were shown on the Disney Channel Asia's 2011 Sneak Peek; however, these were not confirmed images.
- The official website went online on June 17, 2011, and states that there are at least 6 dimensions. All of these (except the 5th Dimension) are shown in the movie.
- The Beak suit is sleeker in the movie.
- A brief teaser trailer for this film was on The Sorcerer's Apprentice DVD. The trailer did not have any new footage nor any new information on the plot, nor did the trailer teaser from Asia.
- The Fourth wall is broken twice:
- During the song Summer (Where Do We Begin?), Phineas begins to sing some of the lyrics from the Phineas and Ferb Theme.
- It is revealed that Ferb leads a double-life as well. Although it could have been a joke or a reference to Phineas and Ferb's double-life with making inventions without their mom knowing, or a reference to the "The Beak" or "Ready for the Bettys".
- Isabella and Phineas kiss for the first time.
- This is the first time that Ferb cries, though it is only briefly shown.
- The Dan Povenmire and Jeff "Swampy" Marsh lookalikes appear.
- Even though this is the longest running Phineas and Ferb event to date, Ferb has fewer lines than he did in others, such as "Phineas and Ferb Summer Belongs to You!", nor are any longer that his lines like in "It's a Mud, Mud, Mud, Mud World" and "The Lizard Whisperer".
- A sneak peek of Summer (Where Do We Begin?) was shown at Times Talks on July 9, 2011.
- This is the first time that the outside of the O.W.C.A Headquarters is shown.
- Carl is seen without his glasses for the first time.
- It is revealed that Carl used to wear braces, and Monogram had black hair.
- Phineas bats left handed. In "Toy to the World" he writes left handed, and in "Phineas' Birthday Clip-O-Rama!" he says that he wants a left-handed flange tuner.

- The baby alien from "It's a Mud, Mud, Mud, Mud World", "Vanessassary Roughness", and "She's the Mayor" appears again .
- The Talking Zebra is shown in an alternate dimension reading a newspaper with a headline that reads 'Kevin Wins Election', a reference to him telling Candace 'I voted for you, Kevin' in "Nerds of a Feather".

Other characters who are shown in the Robot Riot scene but not getting their memories wiped include Irving, Albert, Django Brown, Love Handel, Jenny and other kids (although their memories could have been wiped later or that those whose memories were wiped only include those who knew of Perry's secret).
- Although Jeremy was touring a college with his father that day, he appears at the end of the day to have his memory wiped. (Nevertheless, this error has been resolved since he has been seen with Candace, Baljeet, Ferb, Isabella and Buford as Phineas has been telling them how 2nd dimension Candace took down Norm bots. It is possible that he was told of Perry's secret because of having Perry communicating with Major Monogram without hiding his cover from them, which includes Jeremy, while Phineas was talking. Hence, the brain wiping was necessary

- When Carl shows Perry the watch, behind Perry is a platypus suit. It's color is blue and it only has one glove. But when the hologram of Major Monogram points to the real one, the suit's chest color is white and it has a belt. And when Carl tells Perry the watch also gives and incredible ice cream headache, the suit now has two gloves.
- During Robot Riot, if you compare the extended version and the one that's not, the tree houses impact in different times: in the normal, they collide while Phineas was still battling. But in the extended they impact when Phineas and Perry were in Doofenshmirtz Evil Incorporated.
- Despite of having a normal childhood, Doofenshmirtz-2 knows Balloony, but this is impossible since he drew Balloony due to Doof-1 had no friends in his flashbacks.
- When Phineas-2 sees and hugs Perry the picture frames on the left were re-sized but after the scene Ferb cried, it was back again to its original size. This also included the Flynn-Fletcher frame was also re-sized.

- When Candace drags Linda out of her seat at the movie theater, making their way outside, Linda's pants are fully black.
- During one part of the deleted scene "Inventions Revealed," while the camera zooms in on the inventions, if you look closely you can see a bull from "Robot Rodeo" in front of its platform (look to the right of the pink Tree House Robot's hand).
- It is never explained how the rebuilt Otherdimensionator opened a portal back to the First Dimension, as Baljeet-2 explained that going counterclockwise through dimensions would take a lot of power. However, either Doofenshmirtz could have foreseen this and supplied the necessary power.
- In I Walk Away, Perry is walking down the street and it starts raining quite hard, but when Phineas-1, Ferb-1, Phineas-2, and Ferb-2 go back outside (only a few seconds later), it's not raining anymore. However, it could have been a short burst of rain that happened for a few seconds.
- When Phineas used the remote to close the portal between the 2nd dimension and the 3rd dimension, the crank was on the left side of the remote, but when he used the remote again, the crank was on the right side.
- In Robot Riot, Baljeet's face can be seen, even though he's wearing the Beak costume. In the episode, The Beak, however, the Beak costume covers Phineas' face.

- The Normbots that the Baby Alien ate in Brand New Reality have a blue paint job on their arms.
- When Perry fights Platyborg on Alternate Doof's Building, he punches him and he doesn't flinch, yet when Perry punched Platyborg to protect Phineas and Ferb he walks backwards and crashes.
- Platyborg at first gets hit by a bus, yet after that he is seen on the windshield of a taxi. he could have had flew to a taxi off-screen.
- Before Platyborg salutes to Perry, he sinks into the ground when walking.
- When Platyborg walks into the portal, he walks up some invisible platform into the portal.
- The crack in the screen that Candace-2 made messes up Doffenshmirtz-2's image, yet in other scenes it isn't.
- During the song Summer (Where Do We Begin?):
- Phineas only changed the scene of 1 window in the song to his backyard view. However, 2 windows can be seen changed later.
- The strap hanging Ferb's guitar to his body switched between purple and red during the song.
- The Bible - Alt-Doofenshmirtz is disappointed that no one laughs at his wordplay and comments that it is like "pearls before swine." Jesus uses the term in Matthew 7:6.
- The title is probably a parody of The Adventures of Buckaroo Banzai Across the 8th Dimension.
- The Terminator - Ferb (2nd Dimension) and Platyborg's outfits look like a parody of the Terminator's.

- Star Trek: Doofenshmirtz's goatee is a parody of TOS: "Mirror, Mirror" where the Spock from a parallel universe has a beard.
- The Homer's Odyssey - At the start of the Movie, Ferb is seen with this book opened meanwhile he is sleeping (a weird thing because It's unknown if the book is complete)
- S.W.A.T. - The background music played when the Firestorm Girls capture the boys is similar to the S.W.A.T. theme. The same song was heard in "Isabella and the Temple of Sap", "Finding Mary McGuffin" and "Nerds of a Feather".
- King Kong - One of the giant Tree-house Robots are on the top of a building and pounding its wooden chest, although this was only seen in the deleted Robot Riot scene.
- Star Wars Episode IV - When Jeremy (2nd Dimension) comes to rescue Candace (2nd Dimension), she is posed the same way Princess Leia was when she was captured in the Death Star. Also, Jeremy says "I'm Jeremy Johnson, I'm here to rescue you," similar to how Luke says "I'm Luke Skywalker, I'm here to rescue you" when he breaks into Leia's cell.
- Red Dawn - When Baljeet asks where the bottom half of the beak suit is, Irving can be seen wearing it on top of a pile of defeated Norm-bots yelling "Wolverines" which is the name of the resistance group in Red Dawn fighting the Soviet and Cuban soldiers.
- The Wizard of Oz - Doofenshmirtz-2 releases his Norm-bots in the same way as the Wicked Witch of the West releases her flying monkeys. Earlier, he says, "I've got you and your little friends, too," echoing the famous, "I'll get you, my pretty, and your little dog, too!"
- Final Destination - When Platyborg got hit by the bus, the scene was similar to the infamous bus scene in Final Destination. The only difference is the victim remained alive. (Platyborg was later seen on a Taxi windshield which implies the bus threw him onto the Taxi.)
- The Jeffersons - Phineas mentions moving "on up to the east side to your deluxe apartment in the sky" during his conversation with Dr. D after crashing into his Inator. These are the famous lyrics from the theme song to the long-running sit-com starring Sherman Hemsley (co-written by Jeff Barry, father of Phineas and Ferb writer and Across the 2nd Dimension co-writer Jon Colton Barry).
- Q*bert - One of the dimensions the boys traveled through to return to their own featured the play field from the 1982 video game.
- The guitar riff at the beginning of "Brand New Reality" sounds a bit like the riff from School's Out by Alice Cooper.
- The Silence of the Lambs - At the end as the group is gathered at OWCA headquarters, Dr. Doofenshmirtz is restrained on a dolly in a straightjacket and anti-bite mask, same as Hannibal Lecter was.
- Bruce Lee - When fighting the Platyborg, Perry socks him then shakes his hand in pain—a signature move of Bruce Lee.
- Jane Fonda - In Perry's mug shot he is showing the Black Power salute similar to Jane Fonda's mug sot.
- Vince Vaughn - The actor in That Darn Fiancé looks a lot like Vince Vaughn.
- Jackson 5 - It is possible that Everything's Better With Perry was inspired by the Jackson 5 song "I Want You Back".
- Monopoly - Alt. Phineas and Ferb were playing a game called, "Doofopoly", a parody of Monopoly.
- Sonic the Hedgehog 2/4 Episode I/Generations - In the movie, Doofenshmirtz-2 uses a look-alike robot to try and get rid of Phineas, Ferb, and Agent P using the robot's extending arms. This robot is similar to the Death Egg Robot from "Sonic the Hedgehog 2/4 Episode I/Generations", since it is a look-alike robot controlled by Dr. Eggman which can extend its arms as its main attack.
- Søren Kierkegaard - Buford properly invokes the nineteenth century Danish philosopher with some help from a Victory Gum trading card.
- Fyodor Dostoyevsky - Buford tries to trade off his Victory Gum card honoring the great Russian novelist.
- Codename: Kids Next Door - The Resistance members calling Alt. Candace "sir" may be a reference to the KND members calling Numbuh 362, the supreme commander, "sir," even though she's a girl. Calling superior officers "Sir" was also referenced in Star Trek: Voyager with Captain Janeway quickly stating that she prefers being called "Ma'am" due to her gender. This may instead be a general practice to refer to all superior officers by a single title regardless of gender.
- Santa Claus Is Coming To Town (1970 Movie) - When Dr. Doofenshmirtz gives Alt. Doof his Choo-Choo train and Alt Doofenshmirtz says a similar line to the one when Kris Kringle gives the Winter Warlock a train in the 1970 movie.
- The Great Escape - Alt-Candace bounces a baseball against the wall of the Jailbreak, just like in the movie.
- Battle: Los Angeles - When Phineas takes out the dish that causes the Norm Bots to disconnect and all start falling, it is the same when the US Marines take out the Command and Control Center and cause all the alien drones to fall.
- Georgia O'Keeffe - When the Norm Bot falls to the ground and the skull lands on his head, he says, "Get me - I'm a Georgia O'Keefe painting." This is likely a reference to her 1931 painting, Cow's Skull: Red, White, and Blue .
- Family Matters - Baljeet plays a Polka song with accordion in a same way that Steve Urkel does in "Family Matters". Furthermore, both are dark-skinned, nerds and care about the notes.
- Clifford the Big Red Dog - In the background on a dog food advertisement, a puppy can be seen, it is a bit similar to Clifford when he is a puppy. It can be seen behind the Robot Dog just before the Robot Riot begins.
- South Park - When Alt. Doofenshmirtz talks with the puppet it is very similar to how Mr. Garrison talks when voicing Mr Hat.
- The Simpsons - When Monogram mentions that cannot be called between 3:30 and 4 could be an allusion to "The Simpsons Tree House of Horror V" in which Willie mentioned that his brain can't be read between 4 and 5 because this hour was private.
- Super Smash Bros. series - The dimension that Phineas, Ferb, Candace, Agent P and Doof go into after the 2nd dimension (before Brand New Reality) resembles the stages, Distant Planet and Hanenbow, from "Super Smash Bros. Brawl".
- Xiaolin Showdown - Doofenshmirtz-2 named his robot Norm Bots, possibly thought by Jack Spicer naming his robots Jackbots.
- Hawaii Five-O - As 2nd Dimension Doofenshmirtz enters back into the 2nd Dimension, Major Monogram-2 says "Book 'em ladies!", similar to "Book 'em Danno!"
- Indiana Jones and the Temple of Doom - The mine cart scene closely resembles the scene from the film.
- Nacho Libre - Stacy claims at the beginning of the movie to be a "woman of science," this is similar to Nacho's sidekick Esqueleto saying "I'm a man of science."
- The Elder Scrolls IV: Oblivion - Phineas's attempt to close the Other-dimension-inator is similar to how the players close Oblivion Gates-by taking out their core.
- Paramore - When Doofenshmirtz said "this may be good as it gets" have the similarities to their song Playing God in the bridge.
- Doctor Who - When the robots come out of the portal it is similar to the Daleks coming out of the portal in Doomsday where they also came from another dimension. It is also similar how they travelled through the streets afterwards.
- AC/DC - The tones of voice in the song "Robot Riot" used by Danny are the same used by the band in their song "Shoot to Thrill" and "Back in Black" including the cry at the end of the song.
- The guitar riff at the beginning of "Brand New Reality" sounds a bit like the riff from School's Out by Alice Cooper.
- Paul McCartney and John Lennon - During "Brand New Best Friend", both Doofenshmirtzes wear outfits and have instruments like the ones Paul and John had during their early Beatles years.
To Disney Media
- Kingdom Hearts - The 2nd Dimension City resembles the Dark City in "The World That Never Was".
- Herbie The Love Bug- When Ferb is jumping onto the platypult after Robot Riot when Isabella told him to help Phineas, one of the cars behind him a classic Volkswagen Bug, the same model as Herbie the Love Bug.
- Race to Witch Mountain - When the computer at Perry's lair asks the boys to insert the key. Ferb takes out a whistle similar to the one Seth uses to open the spaceship.
- Kim Possible - Phineas calls Doofenshmirtz "Doctor D", which is what Shego calls Dr. Drakken, and saying "Jinx, you owe me a soda" refers to the fellow Disney Channel original series.
- The Lion King - During "Everything's Better with Perry", Phineas takes Perry in a similar way that Rafiki takes Simba during "Circle of Life".
- It's a Small World - When Doofenshmirtz-1 rides to Doofenshmirtz-2's office, he rides past animatronic scenes that parody It's a Small World.
- The movie was first announced by Jeff "Swampy" Marsh during a January 2010 interview with the Daily Telegraph.

- Movie description from the Amazon press release:
- When Phineas and Ferb accidentally help the evil Dr. Doofenshmirtz complete his latest creation that will finally take control of the Tri-State Area, they get zapped into a new dimension, where they meet their alternate selves! In this new dimension, Dr. Doofenshmirtz is the leader of the Tri-State Area, and even worse—summer vacation doesn't exist! Will Phineas and Ferb figure out a way to get back to Danville, or will they be stuck in this alternate dimension forever?
Editorial Review from Amazon.com:
- Disney TV scored a big hit in 2007, with Phineas and Ferb, the story of two mismatched stepbrothers who share a passion for fantastic adventures and a talent for creating high tech devices. Phineas Flynn is the American chatterbox; Ferb Fletcher is British and taciturn. The television movie Across the 2nd Dimension takes their antics further afield--and spoofs the mania for 3-D. When their giant shuttlecock collides with a spy plane piloted by their pet Perry the Platypus, Phineas and Ferb crash land in the laboratory of Dr. Doofenshmirtz. With typical enthusiasm (and blithe unawareness), the boys help the evil scientist build an "Otherdimensionator" that transports them to an alternate world. As the complications multiply, Perry is forced to reveal that he's not just a pet who grinds his teeth: he's Agent P, part of a cadre dedicated to fighting Doofenshmirtz's schemes. Eventually things get sorted out with the help of the alternate versions of Phineas, Ferb, and their sister Candace. Across the 2nd Dimension is most engaging when it plays like an extended episode of the series, with plenty of humor, off-beat songs, and pop-culture references: Doofenshmirtz and his alternate counterpart perform a number about finally finding a partner as the Blues Brothers, the Lone Ranger and Tonto, and Lucy and Ethel in the candy factory. As is often the case with TV cartoons that morph into features (Hey Arnold, Doug), things occasionally get too big--the swarms of CG robots the alternate Doofenshmirtz dispatches really don't add anything to the story. But the filmmakers generally succeed in walking a fine line, remaining smart without becoming smart alecks. Across the 2nd Dimension will delight Phineas and Ferb fans of all ages.

The movie's initial reviews are generally very positive. It currently holds an 9.9 making "Superb" rating (based on 43 votes) on TV.com. Matt Blum of the Wired.com website claims that "This is truly an instant classic, right up there with some of the best cartoons ever made". Los Angeles Times Television Critic Robert Lloyd enjoyed Phineas and Ferb The Movie: Across the 2nd Dimension as well, noting "a hint of emotional depth, regarding the love between animals and the people who live with them".

DVD Talk's Kurt Dahlke said "It's always a tough proposition to convert a 12-minute cartoon into a feature length movie, but Phineas and Ferb The Movie: Across the 2nd Dimension does the job nicely. Things are padded out a bit with more 'plot' and 'action' than is usual for this clever show, but those things that keep viewers of all ages coming back - tasteful pop culture references for parents, clever dialog, good-hearted characters and fun - are all present and delightful. Plus, the song crafting that makes Phineas and Ferb so much fun for aging rock-fans like me is there too. Maybe not enough, but that's my only complaint. Packed with extras and excitement, this 2-disk fan pack represents true family fun, and is Highly Recommended"  AssignmentX gave the movie an A-, saying "If you haven’t yet had a chance to check out Phineas and Ferb, this is a good starting point. It’s the barometer for which all future made-for-cable animated films should live up to and it once again extends Phineas and Ferb from a fad to what will likely be a very long run."
