Boxers are very isolated - or isolated within their own camps.

I spent so long studying really hard to become a fine actor, but threw it all away because I got the adulation and the fame so easily

Wrestlers are all pretty busted-up by the ends of their careers.

Julian Schnabel painted a picture that he dedicated to my character in Rumble Fish. It was called The Motorcycle Boy. I remember when he brought it over to me at the Mayflower Hotel [in New York] years ago. This is when you and I knew each other.

When I did Sean Penn’s movie, I think I was living in, like, a $500-a-month room, and someone called me up or bumped into me and asked me if I’d come up to work for a day. That sort of got me going a little bit. But it wasn’t until Sin City [2005] that I kind of got back into the game.

Acting was never my first choice as a profession, but I came to terms with it when I decided I better buckle down and be the best I can be at it.

Sometimes, when a man is alone, that's all you got is your dog.
