Movie urban legends everyone believed

Great cinema is like a magic trick: The show in front of you is so real, so convincing, that you never stop to think about what crazy stories must have happened on the other side of the camera. Because of this beautiful mystery, the history of cinema is littered with a wide array of wacky urban legends involving everything from magical curses to on-screen manslaughters to subliminal sex messages that were never there. Many of these crazy ideas have been repeated so often and are now so broadly accepted by the public, that people never stop to think about how silly they really are. Other film myths are so intensely "out there" that it's hard to imagine that anyone ever believed them (but they did).
You've heard these stories before. You've maybe even told some of them yourself, from time to time. Now, finally, here is your chance to learn the truth about these movie urban legends.
