Ratatouille
(2007)

Remy (Patton Oswalt) and Linguini (Lou Romano) are able to create a dish capable of pleasing the cynical food critic, Anton Ego (Peter O'Toole), with some help from Colette (Janeane Garofalo) and Remy's family.  The dish?  Ratatouille, of course.  Ego is introduced to Remy after requesting to meet the chef, and surprisingly, agrees to keep their secret.  Unfortunately, even though Ego writes a glowing review for Gusteau's, the health inspector closes the restaurant down (after escaping from the freezer), due to Remy's presence.  Ego is also fired, but rebounds by opening a new restaurant: La Ratatouille, with Remy as the perfect "silent" partner.  It's a hit, and they all live, well, you know.
[Pixar Cameos] Linguini seems to have a pretty "Incredible" pair of boxers, and Skinner chases Remy through Paris on a scooter made from some of Lightning McQueen's spare parts.
