Pixar’s 2007 animated masterpiece Ratatouille stands out not only for its stunning rendering of Paris and fine cuisine but for a perfectly calibrated voice cast. Bringing a rat with a refined palate and a clumsy garbage boy to life required a distinct blend of stand-up comedians, veteran dramatic actors, and Pixar internal talent.
The core of the movie's enduring success relies heavily on how these vocal performances ground an absurd premise—a rodent orchestrating a human chef by pulling his hair—into something emotionally resonant. Understanding who voiced these iconic characters reveals how the film achieved its rare mix of box-office triumph and critical acclaim.
The Voices Driving the Kitchen
Patton Oswalt as Remy
Comedian Patton Oswalt anchors the film as Remy, a rat with an extraordinary sense of smell and a dream of becoming a French chef. Oswalt brings an earnest, rapid-fire intellectual passion to the character. His delivery makes Remy’s high-minded lectures about flavor combinations feel entirely earned rather than precious. When Remy expresses anguish over human prejudice or pure joy upon tasting cheese and strawberry together, Oswalt infuses the animated rodent with deep humanity.
Lou Romano as Alfredo Linguini
To voice the inept, gangly kitchen garbage boy who becomes Remy's human vehicle, Pixar tapped artist and animator Lou Romano. Romano’s vocal performance captures a fumbling, endearing insecurity. Linguini isn't a traditional heroic archetype; he's overwhelmed, awkward, and desperately trying to keep up. Romano’s natural, unpolished delivery prevents Linguini from sounding like a slick Hollywood protagonist, giving the character his signature charm. Observers at Bloomberg have shared their thoughts on this matter.
Janeane Garofalo as Colette Tatou
Colette is the sole female cook in a harsh, male-dominated Parisian kitchen, and comedian Janeane Garofalo gives her a sharp, no-nonsense edge. Colette has had to work twice as hard to earn her spot under Gusteau, and Garofalo’s raspy, assertive tone communicates that defensive armor instantly. Her famous monologue about kitchen discipline establishes why she commands respect long before she softens toward Linguini.
The Legends and Antagonists
Ian Holm as Chef Skinner
Veteran stage and screen actor Ian Holm portrays the paranoid, diminutive antagonist Chef Skinner. Holm plays Skinner with manic, cartoonish intensity wrapped in corporate greed. His delivery shifts smoothly from sycophantic politeness to sputtering rage as he tries to steal Gusteau’s restaurant legacy. Holm's voice work grounds the physical comedy of Skinner's chaotic chases through Paris.
Peter O'Toole as Anton Ego
Legendary dramatic actor Peter O'Toole brings theatrical weight to the terrifying food critic Anton Ego. With a gaunt appearance modeled after a coffin, Ego requires a voice that can cut through stone. O'Toole delivers lines like "I don't like food, I love it—if I don't love it, I don't swallow" with icy precision. His transformation from a feared tyrant into a man humbled by a simple peasant dish anchors the emotional climax of the film.
Brad Garrett as Auguste Gusteau
Towering comedian Brad Garrett voices the spectral culinary giant Auguste Gusteau. Serving as Remy’s comforting internal conscience, Garrett projects a warm, booming paternal energy. His performance embodies the core philosophy that "anyone can cook," providing a contrast to the cynical environment of the professional kitchen.
Supporting Voice Talent
The film’s depth comes from a robust ensemble of supporting actors who flesh out the Parisian backdrop:
- Brian Dennehy voices Django, Remy’s pragmatic father who fears humans and wants his son to stick to garbage scavenging. Dennehy brings protective grit and generational friction to the role.
- Peter Sohn voices Emile, Remy’s binge-eating, simple-minded brother. Sohn’s jovial, innocent vocal styling provides comic relief and highlights Remy’s alienation from his colony.
- Will Arnett plays Horst, the restaurant’s deadpan, German-accented line cook with a mysterious criminal past.
- John Ratzenberger rounds out the Pixar tradition by voicing Mustafa, the polite head waiter who acts as a bridge between the front-of-house chaos and the kitchen.
Critical Reception and Cultural Impact
Upon its release by The Walt Disney Studios, Ratatouille received overwhelming critical praise, sitting comfortably among Pixar's highest-rated films. Critics lauded the movie for avoiding cheap pop-culture gags in favor of sophisticated pacing, physical comedy, and deep visual storytelling.
The voice casting played a major role in this acclaim. Rather than relying solely on high-profile marquee names for marketing, director Brad Bird chose actors whose vocal textures fit the psychological profile of the characters. The result is an animated film that treats food, art, and creation with genuine reverence, driven by performances that still resonate decades later.
Frequently Asked Questions
Did Patton Oswalt do all of Remy's squeaks and physical noises?
While Oswalt provided all of Remy’s spoken dialogue and internal monologues, the animalistic squeaks, chatters, and sniffing sounds were performed by archival animal recordings blended with vocal effects to keep Remy grounded as a real rat.
Why did Peter O'Toole take the role of Anton Ego?
O'Toole was reportedly drawn to the witty, razor-sharp script and the chance to voice a character who undergoes a profound philosophical shift regarding art, criticism, and creation.
Is Lou Romano a professional voice actor?
No. Lou Romano is primarily a Pixar animator and artist who previously voiced characters in The Incredibles and Cars. Brad Bird liked his natural speaking voice and cast him as Linguini for its organic awkwardness.
How did the cast record their lines?
Unlike many animated films where voice actors record entirely alone in isolated booths, the cast of Ratatouille frequently engaged in group reading sessions when scheduling permitted, allowing for natural overlapping dialogue and organic comedic timing.
