You need to be as clean of a slate as you can be, as an actor. You have to try to be open to every experience.

I think for me with theater, I need to take a break and then fall in love with it again. And then go do it again.

I've always felt kind of safe on stage, protected. I've talked to other performers about this and they feel the same things, particularly in the live arena. I never get nervous going on stage to do a play. Doing film or television I'll have more butterflies.

I'm pretty adamant to do an American accent because you get it immediately.

It's a very organic kind of way that people are discovering it, by word of mouth, which I always think is the best way for things to grow. In terms of the affect it's been having on me, I don't even notice that. It's lovely to be able to talk about a piece of work that you're very proud of, that I think's a complex piece of work and not superficial and has depth to it.

I feel very lucky to be making good work still. The confidence of youth, or that sort of competitiveness you get when you're 22 or 23, the impatience - that's probably been tempered. Hopefully I'm slightly better company.

I was obsessed with Batman as a kid. I did the film in part just to be near the Batmobile. But I also think [director] Christopher Nolan made a very fine, intelligent film.
