Lost star Matthew Fox may play the sweet, caring guy on camera, but off screen, the star has a much darker side to him. The 40-year-old actor, who plays DR JACK SHEPHARD on the hit US TV drama, admits to being deceitful on a daily basis. He confesses, "I'm a liar and a cheat and a thief and the ultimate manipulator. I tell lies every day, man. "And when I say I'm phenomenally manipulative, I am." Giving an example of his persuasive ways, Fox adds, "I really enjoy social boozing, and what I enjoy about it is when people I know and care about say and do things they normally wouldn't say or do. To make that happen I'll instigate anything."
