If you're working with someone who you get on with and you're supposed to hate them on the screen, then you get this playful challenge thing where you're trying to one-up each other and that's really interesting. Sometimes it can become like tennis. The harder you hit the ball back, then the harder the hit it back to you.

I've always had an incredible interest in the villains, which are a lot more fun to play.

What's weird is to hear someone else talking about your mannerisms.

I loved working with Mickey Rourke. He's a wonderful kind of crazy.
