His personal quote "Acting is a lot of fun, it's like Halloween every day. You get a costume, a new face, a new identity but at the same time, you've got to be yourself. If you're putting on a fake personality, there's no way you're going to be able to keep up both that personality and also play the role you're supposed to play. You have to be comfortable with yourself."
