I have a reputation for being an improvisational actor, which is true, but I also know what I'm doing so that if the improvisational strand doesn't work I can go back to what I know's already there.

Each performance and each film is what it is. It's right and belongs within that moment. You look at it and try to make it fit your particular part of your character and your particular film.

I like to be working and moving - the worst thing you can do to me is stick me in a room all day while you're lighting a shot. That just kills me.

Guys, particularly in the West, go to the gym and train for hours and hours to pick up something that is heavier than them. Why would you want to do that?

The script will point you in certain directions and I go the opposite if I can. I try do do one thing and tell a different story with my eyes. I believe what's more interesting is always what's not being said.

The more people know about an actor the less convincing they become. A bit of mystery's a good thing.

I played a maniac fan who murders a policeman and she did my makeup. I thought anyone interested in me looking like that must have genuinely liked me.
