Tree House of Horror V - S6-E6

Question: Homer travels back in time and causes changes by what he does in the past, like stepping on a bug. I once saw a movie with the same basic plot: some people travel back in time and are told to be careful not to disturb anything, but when they return to their time everything has changed. In the end they discover it was because they stepped on a butterfly. Does anyone know the name of this movie?

Answer: I'm not sure if this is the one you're thinking of, but an episode of "Ray Bradbury Theatre," called "A Sound of Thunder," dealt with a similar matter: a group of hunters travel back in time to hunt dinosaurs, only to find things have changed when they get back because someone stepped on a butterfly.
