I like stories that exist both in the naturalistic world and in our imaginative lives, films are so immersive in that sense, we can explore how our characters think and dream, as well as how they exist in the real world.

Sometimes the things I learn making paintings or drawings - composition, colour, expressionism, texture - can directly influence the making of a film. Sometimes it's great that they are different, and simply taking a break from one medium to spend time with another, recharges the batteries and I feel refreshed.

I've always liked making things that don't deny the medium that they're made in. If it's collage, I'm happy for it to look like that. If it's a film made with computers, I don't mind that it looks like a film made with computers as long as it still has a feeling or a mood or an atmosphere that is relevant.

When you just get fantasy stories that are about fairies or goblins, I just don't care. I'm never going to meet a goblin, it doesn't mean anything to me. So my definition of fantasy is very broad, it's anything to do with memory, or dreams, or ways of interpreting or making sense of the world.

There is nobody who is good or bad, it's just not like that. They all are complex individuals. They all see the world in their own way that makes complete sense to them. Nobody goes around feeling that they're evil - they think that they're doing the right thing. And so that seems to have something really important, big, and deep to say about human beings.

I kind of enjoy the limits. If you've got no limits, you can do absolutely anything, it's very difficult, actually. I always enjoyed working with machines like color photocopiers and letter-pressing type settings, things where the limits are very apparent. You push the machine to do something, and it tries to do its best, and it usually has wonderful qualities all of its own. Then you get a sort of dialogue going, and the limitations become qualities.

Film gives me live actors, editing, music, sound, a huge and powerful toolbox to play with. If there is a problem for me, it is that film gives me too much. There is less room for the audience to add their side of the conversation.
