Chicken Little 2: Mission to Mars is an unproduced sequel to Chicken Little. According to the book Chicken Little: the Essential Guide, it was going to be a sequel, but that never came to fruition, so the video game Chicken Little: Ace in Action serves as an actual sequel to this film.
Tod Carter recalled on the film's production:
“Not long after that project was shelved, I received a call from Klay Hall, who was directing Chicken Little 2. He was given the mandate to create a story reel for his project in the same time frame that we did for Aristocats 2. I don’t think he or the other board artists at Disney were too excited about the deadline, but I guess Klay figured that it would be a good idea to get someone involved who had actually had experience working at this pace. Overall, the script for Chicken Little 2 was pretty good and I felt great about the sequences in which I was involved. Klay gave me a good deal of freedom to invent and I really appreciated working with him and loved the project.
In the story, Chicken Little finds himself in the midst of a love triangle. On one side, is his childhood sweetheart, Abby “Ugly Duckling” Mallard. On the other side, is the very attractive newcomer, Raffaela, the French sheep. Abby’s at a tremendous disadvantage here, so she goes to great lengths to give herself a makeover. A portion of the makeover sequence is represented on my website, which shows Abby’s grand entrance at school with her new-found look. The script, in this case, had dialog but very little specific action, so most of the visuals and business are original ideas that I was free to invent. Working on this type of scene is great fun for an artist.
