Trivia: Near the beginning, when Remy is in the sewers and begins to make his way up to the skyline of Paris, he is startled by a barking dog in one of the apartments. If you pause and look at the silhouette of the dog, it greatly resembles Dug the dog, from the 2009 Disney/Pixar release Up - another precursory nod to an upcoming movie by Pixar. (00:16:35)
Continuity mistake: Right before Chef Skinner exits the kitchen, in an attempt to stop the soup from being delivered, there is no ladder to the right of the door. Then when he re-enters the kitchen, a ladder appears next to the door. (00:25:40)
Trivia: When Skinner stops chasing Remy, a mime artist is visible in the background. This man is none other than Bomb Voyage, a character from The Incredibles, Pixar's previous production. (01:17:30)
Continuity mistake: At the beginning of the film, Remy and Émile are at the old lady's house. The cooking show comes on TV. In one shot, the TV is facing straight forward, sitting perfectly parallel to the edge of the cupboard. In the next shot, the TV has moved to the left and is sitting at an angle. Watch its relation to the edge of the cupboard.
Trivia: Once again, another reference to "The Incredibles": before Remmy & Linguini go into the kitchen for the first time, Linguini pulls his pants open, and we can see his boxers. His boxers, have the Incredibles logo on them.
Continuity mistake: Remy is reunited with his father in Paris. They are in a conversation at a little table. Remy's 'cup' moves closer to the edge of the table, towards our left, in several shots.
Chosen answer: This is a legend, which states that the number of pleats on a chef's hat (or toque) represents the number of ways that they know how to prepare an egg. There's certainly no evidence that it's actually true - it would be highly impractical if it were, requiring a chef to get a replacement every time they learned a new method. Regardless, many toques are made with exactly 100 pleats, supposedly based on the idea that there are 100 ways to prepare an egg, however, chefs wear them regardless of their culinary skill in that department.
