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.

One thing I will say - my job gets harder and harder. The more you understand about what you are capable of, the less the instrument can do it physically. It's an inverse equation, if that's the right phrase. I just slammed those two words together. It sounded right.

It's a nightmare to sit and watch a film that I'm in. There's a horrible inescapability to it.

I'm a quite serious actor who doesn't mind being ridiculously comic.

Any actor who judges his character is a fool - for every role you play you've got to absorb that character's motives and justifications.

What's interesting about the process of acting is how often you don't know what you're doing.

I was coming from a very cerebral, dark, difficult, layered play by Christopher Hampton and doing an action movie in Hollywood (Die Hard) with explosions, and I was holding a gun.
