I'm guessing from the fact that they list the lead actor/actress in every other film that this and Brad Garrett are just the quiz author mistakenly assuming that the biggest-name actors in a production are very important. Enchanted should really be Amy Adams. Ratatouille should really be Patton Oswalt.
It's a little weird to have Brad Garrett as "starring" in Ratatouille, isn't it? All of the other hints are either leads, second leads, or primary villain (in the case of Susan Sarandon), but Garrett has a pretty small part.
