The 36-year-old wishes there was an air of mystery around more celebrities. He tells American magazine GQ, "The better the actor, the less you know about his life. "I mean, nobody's better than (Robert) De Niro, and you don't know anything about him, right? Look at Meryl (Streep). We don't know s**t about Meryl. Look at Clint (Eastwood). And Jack (Nicholson). And Brando. Marlon Brando - who f**king knows, right?"
