I never expected to have any kind of film career, to be honest. It was all a bit of a surprise. But I was in a big hit play on Broadway. America, as many people will say, says yes more often than we do. And so I was suddenly surrounded by people saying yes. But I was aware that was 'cause of what I was in. It had a big impact.

You try to find things that are challenging and interesting and hopefully it will be the same to the audience.

I approach every part I'm asked to do and decide to do from exactly the same angle: who is this person, what does he want, how does he attempt to get it, and what happens to him when he doesn't get it, or if he does?

I think there's some connection between absolute discipline and absolute freedom.

I'm still living the life where you get home and open the fridge and there's half a pot of yogurt and a half a can of flat Coca-Cola.

Snow Cake is a lovely film. Really proud of that. We shot it in 21 days. I thought Sigourney was amazing in it. And very, very accurate. I think there was some element that thought she had pushed it too far. But not at all when you do the amount of homework she had done and spent the amount of time she did with adult autistics. She was right on the money. And I think Marc Evans is a terrific director. He's a sweet, open, honest man and a really good director of actors.

Film has to be reflecting the world that we live in, and that's all you want to be a part of. Actors inhabit the same planet as everyone else. It's a weird thing that happens when you're an actor because people hold you up because you somehow embody in parts groups of people or people's hopes or something.
