I've had a lot of different responses to my films. I got a lot of support from 'The Piano,' the obvious one, but it feels like an ocean, with a lot going on - the goal is to keep alive.

That's just how I see things on a base level: there's so much going on. Or at least I like to have that feeling. It's part of being interested in notions of reality apart from storytelling. I don't know if it has something to do with having an art school education, which makes you aware of the way visuals speak, or makes you trust them more.

What I have learned from my work up to now, is to try to be open, but also protect myself by not letting the good and the evil get too much importance.

Between 18 and 26 I acted professionally, on the stage and a little bit on television. Acting is okay, but it's quite pressurized. Then I went to England - I wanted to reinvent myself.

Actual violence has no attraction for me at all.

If you start with a good idea, you can encapsulate it in a phrase and explain it. I like high-concept films. Everyone can get hold of it. I don't think there's any harm in that at all.

I took four years off after 'In the Cut' because I wanted to see who I'd be without work. I even tried being a hermit in the wilderness in New Zealand. I stayed in a warden's hut two-and-a-half hours off the Routeburn Track through the fjords on the South Island. It was early winter, so there was no electricity or running water.
