Op said inspired, not influenced. I'm sure the board room thinking of fun things to add to everything everywhere all at once random sequences pitched 15 different movies, and ratatoille was one that was mentioned. I think they were "inspired" by the idea of someone on someones head controlling them.

I know what you mean, of course thematically they aren't similar at all. But, since it's a list of movies that contributed to the content or were referenced in EEAAO, I think inspired is a fine term to use as a blanket for all of them.
