Actors use who they are to be someone else, but I would hate to ever think I'm playing myself. It's imagining being someone else that is the key motivating thing for me. So when people want to know about me, it makes me a bit unnerved.

I don't feel I'm playing villains all the time.

Kenya doesn't have much of an infrastructure for hosting a film of this scale. Our producer decided that for the film to really work it had to be in Kenya.

I loved doing Harry Potter. I had a great time on that. And I think it's good to have a mix. I think you're learning all the time.

I have a great editor and I enjoy, in a masochistic way, being ruthless about my own performance. How do I know, but I think I'm quite good at saying, "That's no good. That's no good. That's it. That's it. That's good." And I'm with the editor who goes, "No, I think you're wrong. That's not your best." There's an initial point in the editing, if you're directing yourself, especially in my case, where you go, "Ouch, ouch, ouch, I can't watch this." And then, there's a point where you become hard-nosed and just take your neurosis away and go, "What's working? That's okay. That's okay. We can lose that, and lose that." You get objective about it.

When you meet women, don't pretend to be anything that you're not.
