While some may wonder whether he lost a part of his youth to the fame and success of Harry Potter, Radcliffe seems to have no regrets about the nearly all-consuming project. "They've been great. For the most part I've been happy every single day. And all the times I've been unhappy, it's never been anything to do with Potter," he told Details magazine. In later interviews, Radcliffe admitted that he had a drinking problem during his teens and occasionally went to film scenes as Harry Potter still drunk from the night before. He has been sober since 2010.
