Michael Moore has urged audiences to "rise up out of their seats" and take action against politicians cheating them of proper healthcare. The Oscar winner's latest documentary, Sicko, is an expose on the U.S. healthcare system but Moore insists he's leaving the hard work in his campaign to those who watch the movie. Speaking after a screening at the Cannes Film Festival in France, Moore told reporters he had deliberately avoided confrontations with those responsible for the problems he highlights. He said, "I'm tired of all the yelling and screaming. It wasn't getting anywhere. "I didn't want people think, 'As long as Mike goes and beat them up, I can sit here and cheer him on.' "I want the public to rise up out of their seats and be called to action, rather than for me to do it."
