From his exceptional previous features ("The Iron Giant" and "The Incredibles") through this one, Bird has refused to ghettoize himself, refused to back off from his passion to make movies whose animated surface doesn't stop them from touching the same emotional bases as live-action fare. When Pixar executive producer John Lasseter says, "There's a level of depth, complexity and humor to this film that I don't think any Pixar film has had before," he's not giving in to hyperbole, he's getting at the heart of Bird's concerns.
Whereas the tendency in so much of today's animation is to be glib and on the surface, "Ratatouille" and its Pixar brethren have carved out a place for themselves by being genuinely smart and sophisticated in ways that please audiences as much as critics.
"Ratatouille" also takes full advantage of what the medium of computer animation offers. As much as story, director Bird and his team love great chases, wild rides and wacky adventures, and setting this film both in a breathtakingly beautiful Paris and the unnerving sewers beneath the city offers ample opportunity for all manner of visual play.
Although mice have been members in good standing of the animation community at least since Ub Iwerks drew Mickey Mouse in 1928, the idea (which started with animator Jan Pinkava, who shares a story credit) of making a rat the hero of a major motion picture is a lot nervier than having penguins or other cuddly folk in the first position.
And, to its credit, "Ratatouille" is surprisingly candid about letting rats be rats. Yes, our hero Remy walks on his hind legs (the better to keep his front paws clean for eating) and has a face as expressive as that of a Yiddish theater actor, but his fellow rats swarm in such realistic packs it is a real gut-check to see them scurrying about. And asking audiences to accept them as heroes is a riskier gambit still.
Yet this is exactly what Bird and his gang accomplish. They've made "Ratatouille" so imaginative, good spirited and funny that it not only blurs the line between reality and fantasy, it manages to blur it between species as well. And it does it all, an amusing "Quality Assurance Guarantee" boasts in the closing credits, with "100% Genuine Animation! No motion capture or any other performance shortcuts were used in the production of this film."
Of course, it doesn't hurt to have a character as endearing as Remy (winningly voiced by comic Patton Oswalt) as a protagonist. Someone with the soul of a poet as well as such a highly developed sense of taste and smell that his father uses him as a poison tester, Remy ignores his family's garbage-eating proclivities and insists, "If you are what you eat, I only want to eat good stuff."
Remy's hero is the legendary Parisian chef Auguste Gusteau, whose "anyone can cook" motto he takes to heart. Gusteau, sadly, is no longer among the living, done in by, among other things, the acid words of cadaverous food critic Anton Ego, a.k.a. "The Grim Eater," splendidly voiced by the man Bird wrote the part for, Peter O'Toole.
Several tricks of fate bring Remy not only to Paris, but to Gusteau's itself, now run by the villainous Skinner (Ian Holm), an entrepreneur more interested in selling over-hyped frozen food than running a great restaurant.
Also arriving at the same time is Linguini (Lou Romano), an awkward young man, the son of a former employee, who dreams of chefdom but who has no discernible talent in that area. Hired as a garbage boy, his chances of advancement are nil. Until he meets Remy.
One of the joys of "Ratatouille" is watching as these two discover that they need each other — Linguini can't cook without Remy's guidance, and Remy wouldn't be allowed to set foot in a kitchen without Linguini as a front man — and then painstakingly construct a Rube Goldberg system that allows them to work together without speaking the same language.
Making the whole thing stranger still is that Remy is in constant communication with a vision of the late great chef Gusteau (Brad Garrett of "Everybody Loves Raymond"), who doesn't let being a figment of Remy's imagination stop him from giving great advice.
Also sharing kitchen wisdom was real-life master chef Thomas Keller of Northern California's French Laundry, who contributed to "Ratatouille's" impressive accuracy about how restaurants operate. He designed the film's signature dish and even got to voice the part of an eager patron.
"Ratatouille's" plot offers numerous twists, turns and surprises, but perhaps none so impressive as its refusal to soft-pedal the ages-old antipathy between rats and people, the generations of mistrust and disgust on both sides. Getting a leopard to change its spots would be nothing compared with what the characters are asked to do here.
It is the film's ability to build those characters, to construct recognizable individuals we can invest in, that is the heart of "Ratatouille's" success. Even when a voice as well-known as that of Janeane Garofalo, who plays a chef named Colette, is heard, it's the character we are listening to hardest, not the celebrity. In an animated film, you can't ask for more than that.
