Ratatouille (film) - Voice Cast - Main Characters

Main Characters

• Patton Oswalt as Remy, a rat who strives to serve a grander purpose in life. Director Brad Bird chose Oswalt to voice after hearing his food-related comedy routine. Remy was named after director Brad Bird's dog, an American Hairless Terrier.
• Lou Romano as Alfredo Linguini, the son of Auguste Gusteau and Renata Linguini. He is hired as the restaurant's kitchen cleaner, but befriends Remy in the process.
• Janeane Garofalo as Colette Tatou, Gusteau's rôtisseur. She is assigned to tutor Linguini in cooking, later becoming his girlfriend.
• Ian Holm as Skinner, a diminutive chef and owner of Auguste Gusteau's restaurant. He plans to use Gusteau's name to market a line of microwaveable meals. Skinner's behaviour, diminutive size, and body language are loosely based on Louis de Funès.
• Brian Dennehy as Django, the father of Remy and Emile and the leader of the Rat Colony. His name is never mentioned in the film. Dennehy, during the 1980s, had previously worked with Disney on films Never Cry Wolf and The Man from Snowy River II.
• Peter O'Toole as Anton Ego, a restaurant critic. He openly dislikes Auguste Gusteau's methods and opinions. Ego's appearance was modeled after Louis Jouvet.
• Brad Garrett as Auguste Gusteau (whose first name and last name are anagrams of each other). The once greatest chef in France until his death by heartbreak caused by Anton Ego's negative review of his restaurant. Many reviewers believe that Gusteau is inspired by real-life chef Bernard Loiseau, who committed suicide after media speculation that his flagship restaurant, La Côte d'Or, was going to be downgraded from three Michelin stars to two. La Côte d'Or was one of the restaurants visited by Brad Bird and others in France.
• Peter Sohn as Emile, Remy's brother, who does not share his brother's passion for cooking and eats whatever he can find out of the garbage. He is also a thief.
