Catherine Keener really gets me. She and I have such a shorthand together.

I'd rather go for Scorsese and De Niro. I just think he was so much better.

What are we taking from people and what do we give is a life-long struggle, I think, for most of us. Who are we? Do we like who we are? Do we know who we are? Do we care? Does anyone care? That's such a big topic. I could tackle that in many movies. So could other people.

I never get tired of looking at her [Catherine Keener] and it always surprises me, despite how many hours of film I've shot on that face. She's fantastic. She does comedy and tragedy so equally well. She wears her feeling so on the surface for both. I try to stop myself from casting her but I just keep coming back to her. She's just so fantastic to work with.

Filming is a funny combination of having a good time and not being able to wait until its over.

I guess I always knew going into the movie that casting that part would be difficult. Oliver just felt likeable. I felt it would be hard to dislike this man. I don't know why, but I'm sure other directors have felt the same when casting him. Oliver is goofy yet formidable, smart but likeable... I didn't want the character of Alex to be nasty or demonised. I wanted him to be struggling with his actions.

You can't take your stuff with you when you die. That doesn't mean you shouldn't enjoy it while you're alive. Why not? But it's all pretty silly. I fall victim to it. I mean, I want nice stuff too. So I guess I'm poking fun at myself as well as other materialistic people.
