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.

Certainly as actors, and maybe as directors, you've got to hang on to something childlike. You've got to know what play is. I haven't worked with Mike Leigh, but I know him very well and there's something open in his eyes about what's in front of him. And the same is true of Alfonso in a Mexican, mad way. There's an enthusiastic response to something. Neil Jordan, the same, when he gets excited . You just want to know there's a human being in there.

Being on the stage in New York is always exciting because you feel like you're part of the life of the city.

Those of you who are not aware of my brilliant career as a stand up comic, I'm not aware of it either so we might well wonder what we're doing here.

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

I knew with Snape I was working as a double agent, as it turns out, and a very good one at that.

What is it about actors? God knows I get bored with actors talking about themselves.
