In 2006, Clooney made headlines as People's sexiest man alive. But this year, the Oscar winner made news for his continued push to stop massacres in Sudan. Just weeks after attending the Oscars, Clooney was in Sudan to document deaths in the country's Nuba Mountains. He then testified before Congress and was arrested after a protest at the Sudanese embassy. "Our job right now is to try to bring attention to it," Clooney said, "and one of those ways was, apparently, to get arrested."
