We've all seen what happens on the screen -- blood-pumping action sequences, tear-jerking moments and breath-taking dramatic scenes -- but when the camera turns the other way, that's when things get even more fun.

It was during a behind-the-scenes moment of 'Terminator Salvation' that Christian Bale let loose a rant so outlandish that we're still talking about it now. It was after Quentin Tarantino yelled "cut!" on the set of 'Kill Bill, Vol. 1' that Uma Thurman broke down laughing with Lucy Liu over her severed scalp. And these moments are just as iconic as the movie scenes themselves.
