- “In many ways, the work of critic is easy. We risk very little, yet enjoy a position over those who offer up for their work and their selves to our judgment. We thrive on negative criticism, which is fun to write and read. But the bitter truth we critics must face is that in the grand scheme of things the average peaceful junk is probably more meaningful than criticism designating itself. But there are times when a critic truly risks something, and that is in the discovery and defense of the new. The World often unkind to new talent new creations, the new needs friends. Last night, I experienced something new an extraordinary meal from a singularly unexpected source. To say that both the meal and its maker V honors my preconceptions about frying, cooking is a gross understatement, they have rocked me to my core. In the past, I have made no secret of my disdain for Chef Gusteau's famous motto, "Anyone can cook" But I realize only now I truly understand what he meant: Not everyone can become a great artist, but a great artist can come from anywhere. It is difficult to imagine more humble origins than those of the genius now cooking at Gusteau's, who is in this critics opinion, nothing less than the finest chef in France. I will be returning to Gusteau's soon, hungry for more!”
- ―Anton Ego's speech
The name Ego is from the Latin meaning of "I" or "self", but is now associated with egotism (narcissism) or egoism (self interest). This would allude to a certain level of vanity and arrogance on the part of Anton. He has nothing but contempt for the people around him combined with a cruel sense of humor and something of a sadistic streak. However, unlike Skinner, he is not presented as a man of pure evil. He shows a great amount of humility and indeed sentiment after eating Remy's dish of ratatouille and learning the secret of Gusteau's restaurant.
Ego is extremely passionate about food, claiming, "I don't like food, I love it", and claims to refuse to swallow food that he doesn't like, which explains why he's so thin.
He is a man of great taste and distinction, showing a knowledge of fine wines as well as food.
Ego is intelligent and sophisticated and in terms of dress sense, completing his dark, dapper suit with a chic scarf.
Ego is an imperious and acerbic food critic, whose reviews can make or break a restaurant. He adamantly rejects Gusteau's belief that anyone can cook, and was a firm critic of the idealist chef. Following a harsh review from Ego, Gusteau's restaurant was downgraded from five to four stars. Gusteau died mysteriously soon after. The restaurant then lost another star with his death. In his career-killing review, he compared Chef Gusteau to the rather pathetic Chef Boyardee.
When he had heard that Gusteau's was rising in popularity with Remy as the cook, he personally offers a challenge to the restaurant in which they must deliver "their best shot" to impress him. Remy serves a simple peasant dish, ratatouille (a play on words and the title namesake) which is so brilliant it reduces Ego to his childhood memory of his mother cooking. Tears flow from his eyes, and when he requests to see the chef, Linguini and Colette tell him to wait until after the customers have gone. When closing hour is struck, Linguini reveals Remy. Ego initially believes it to be a jest, but after hearing Linguini explain and viewing Remy perfectly recreate the dish, he thanks them for the meal and quietly leaves.
A changed man, Ego finally understands what Gusteau meant: While not everyone can be an artist, true talent can be found in the most unusual place. He presents a shining review of the restaurant, and in particular, the chef (whom he does not name). Ego then loses his job and credibility as a critic when Gusteau's is closed down due to the presence of rats, but now leads a successful and a happy life as an investor and regular patron of the small bistro La Ratatouille, with queues around the block and where the cook is a small rat. Anton Ego is an example of a realistic villain, one who faces adverse action or reformation, rather than simply getting destroyed at the end.
- Anton Ego appears to be loosely based on Giulio Andreotti, the Italian Prime Minister and recent subject of the film Il Divo. They are very similar in both speech and physical appearance and both strike fear into those whose lives they can influence.
- Ego is most likely a mixture of traits borrowed from the late horror actor, Vincent Price and British art critic, Brian Sewell.
- Ego's appearance was modeled after Louis Jouvet.
- Ego is also known as "The Grim Eater" within the press.
- At one point in the film, you can see Bomb Voyage as a mime in the background. There is a young boy watching him do his tricks, and if you look closely, you can see that it is young Anton Ego (From Ego's flashback).
- Anton's office is shaped as a coffin and his typewriter seems to have a skull motif on it, setting the mood of the character.
- Despite being French, the name "Anton" is German, Dutch, Scandinavian, Slavic, and Romanian rather than French. Many French people use the name "Antoine" which is also a form of the English name, "Anthony."
- Ironically, the name means "beyond praise" despite his critical nature.
- Ego can also be compared to critic Simon Cowell: both are extremely blunt and deliver especially harsh criticism to any performances that do not please them; both have nicknames associated with the Grim Reaper (Ego is called "The Grim Eater," while Simon has occasionally been called "The Grim Reaper"); and their critical reviews tend to "make or break" people.
