For a film to be viable, it has to survive this process of scrutiny. I think most filmmakers have obsessive-compulsive tendencies and would be completely unemployable in any other job - so it's great to be able to channel your psychological anomalies into something productive and creative.

I love America, but I've now got two young kids and America has changed so much since 9/11 and Bush. It's beyond Orwellian. The idea in '1984' that if you keep saying you're being attacked then you can get away with anything has come true.

What I look for when I see a piece of art for the first time is some kind of emotional, intellectual experience, that's a combination of both of those things and is informed by my knowledge and something new that I see the artist doing.
