Ethan Hawke is opening up about the end of his five-year marriage to

Uma Thurman, which can only mean one thing: The dude's got a movie coming out. In an interview on tonight's 20/20, the star of the upcoming Taking Lives admitted that career pressures contributed to the split. "I don't know if it's just too hard to be married to a woman that wants to be a movie star," he said. "I know that she has that right to want that."
