when i first saw lion king, and mufasa (sp) got trampled by the bulls, it wasn't bad, but when Samba walks over and nudges the body, i thought about all the movies with great vomiting scenes. the best two i can think of are monty python's meaning of life and team america, world police.
Bad Taste. If you haven't seen it you need to. Watch that and then lord of the rings and see just how far P. Jackson has come with his film making.
Four Rooms. The closer the shot of the vomit coming out of the mouth, the better the vomit scene is...
damn, you just reminded me of another great scene which i should post in that other thread "Favorite Movie Scenes". four words: lighter, thumb, chopper knife
