'Suits' fans. I've never met a more diverse audience: across gender, race, class. It's incredible. People who are high-powered lawyers to doormen. A Chinese immigrant cable installer - who barely spoke English - loves 'Suits!'

It's a hard thing for me to wrap my mind around the C word: celebrity. Rock stars are celebrities because they're larger than life. As an actor, you have to play the everyman and the everygirl. If you start treating people in the real world like assistants, that's not a good look. But my friends keep me grounded.
