In the charming Pixar film Ratatouille, a rat named Remy is inspired by a famous cook who says that "anyone can cook." In the end, the rat is vindicated, and becomes the chef at a French restaurant.
The story evokes the American value that with hard work even someone from a lower class can achieve greatness. The theme of the film, "anyone can cook," resonates when even a rat, with sufficient ambition and wiles, can make it big.
What most people ignore about the film, though, is the complete inability of the other main character, Alfredo, to learn to cook, in spite of having the same ambition, and, indeed, extensive exposure to good cooking practices.
In the story, Remy secretly uses Alfredo as a puppet to cook (see the picture). In this way Remy's cooking gains acceptance--nobody would give a rat the same chances they'd give a human. But even by the end of the movie, Alfredo is incapable of making a decent meal on his own.
What's the difference between Alfredo and Remy? It appears to be some kind of in-born talent, which is at odds with the theme of the film.
Anyone can cook. Except you, Alfredo. You just don't have the right stuff.
