I'm not sure about your second use. I don't think I would expect someone to fall for a film. In the context of "to like a lot", it's normally something that happens between two people, not a person and an inanimate object.
We also "fall for" a trick or a practical joke.
Someone tried to tell me once that spaghetti grew on trees and I fell for it (hook, line and sinker).
