1.Ratatouille is packed full of small but impressive details about the food service industry. For example, Colette has an oven rack burn on her forearm, a very common injury among professional chefs.
2.The same goes for the scars on her fingers.
3.Also, as Chef Skinner finishes pouring Alfredo a glass of wine, he gently twists the bottle. This pour technique is used to prevent wine from dripping down the sides.
4.Oh, and anyone who's chopped a vegetable will instantly recognize the green stains left on the cutting board after Alfredo is finished chopping leeks.
5.When Remy enters the kitchen, he washes himself thoroughly with soap and water (as any serious chef would)...
6....and afterward, he spends a lot more time upright instead of on all fours to keep his two front paws clean.
7.This movie also takes its continuity very seriously: Alfredo has a bite mark on his hand from where Remy bit him earlier on...
8....and there's a section in Gusteau's cookbook that labels each chef's job in Gusteau's kitchen. Remy studies this part of the book early on in the movie, which explains why he knows this information later on.
9.At one point, the food critic Anton Ego states, "I don’t 'like' food, I love it. If I don’t love it, I don’t swallow." This is especially significant because he's a little fuller in the face at the end of the movie than he was at the beginning, which suggests that the food has improved!
10.Speaking of Anton Ego — who strikes fear into the hearts of chefs — he has a typewriter that resembles a skull...
11....and an office that resembles a coffin.
12.Ratatouille is also packed full of Pixar Easter eggs: Bomb Voyage from The Incredibles makes a very brief appearance in the background of a scene...
13....Alfredo is wearing underpants adorned with The Incredibles logo...
14....and Remy is chased off by a dog that looks suspiciously like Dug from Up when he's exploring the apartment building.
15.Speaking of the apartment building, Remy also sees a woman pointing a gun at a man. A moment later, the couple end up kissing. Later on, when Colette is about to mace Alfredo, Remy makes him go in for a kiss.
16.Oh, and the kissing couple? You can spot them later on when Skinner falls into the Seine.
17.When Skinner is reading about Alfredo's success, there's another bit of news that made the front page: "Belligerent Man Jumps in Seine." It's about Skinner, who ended up in the river after trying to chase down Remy.
18.Did you notice that Remy drinks from a toothpaste cap?
19.Oh, and at the end of the movie, Remy opens a rat-size bistro. Look closely and you'll see the chairs are teacups, the tables are ramekins, the plates are buttons, the utensils are pins, the lights are Christmas lights, and the umbrellas are cocktail umbrellas — did we miss anything?
20.Finally, you might be familiar with the fan theory that Remy grew up in Anton's mother's house and, therefore, learned to cook by watching Anton's mother (which would explain why Anton loves Remy's ratatouille so much).
21.HOWEVER, the film's director has since stated that any similarity between these houses is 100% accidental.
