Joaquin Phoenix. After a stint in rehab, Phoenix unluckily got into a serious car accident, wherein his car flipped over several times. He said that while he was trapped in the car with no way to see, he heard a man's voice telling him to "just relax." He responded that he was relaxed, and the man said, "No, you're not." The mystery man also prevented him from lighting a cigarette, which may have caused an explosion. The biggest twist? The man in question was director Werner Herzog.
