By "last movie", do you mean the previous movie? The only unusual thing she did in Bender's Game was kiss Leela. Certainly a step up from rebounding with Zapp Brannigan in the second movie. Besides, it wasn't really even Amy. Only Fry and Leela were truly themselves. Everyone else was a character in Bender's mind. Or do you think that Hermes is really a pacifist hermaphrodite in the regular world, too?
If "the last movie" means the final movie, then I'm drawing a blank. She didn't do anything "unsavory" that Leela wasn't even more guilty of. Heck, Lauren Tom beating the crap out of David X. Cohen in the making of documentary was worse than anything Amy ever did.
