Nicolas Cage: Everyone’s favorite actor to make fun of actually gets really into a lot of his characters. For “Ghost Rider,” he painted his face constantly and carried Egyptian relics to try and tap into the world of actual ancient ghosts. (Okay, that’s not surprising.) He also refused to speak to his co-stars during filming so they would be afraid of him. For “Leaving Las Vegas,” he liked to get drunk and record himself so he could see what he would actually look like intoxicated. The most extreme, however, was for “Birdy,” when he had two teeth removed without anesthesia.
