Actor Matthew Fox saw his career take off in the 1990s with the role of Charlie Salinger in the American TV series "Party of Five," and he gained even more popularity as Jack Shephard, the central character in the innovative series "Lost." Now, though, his performance in the movie, "Emperor," in which he plays the role of U.S. intelligence officer Gen. Bonner Fellers, who investigates the wartime guilt of Emperor Hirohito (posthumously known as Emperor Showa) is surely his biggest movie role to date, coming as it does after 2008's "Vantage Point."
