I think there's something in collaboration - the fact that you can sit there and bounce ideas off of someone. It definitely matters who the person is, because certain people... The act of collaboration, where you can talk to someone, hang out, get ideas going, there is something in that. That's similar between everyone. But I think every individual collaborator is different, because they have different brains and emotions and ways of working, so it changes. Definitely.

I have a team, the same team of filmmakers I worked with on 'Pi' and 'Requiem'. Which is my cameraman, and my composer, and my producer. We've all worked together for a number of films.

I only want to work with actors that really get it and make it work. I didn't want it to be a star-driven thing anymore.

CGI means, just to be clear, creating any type of image with a computer. Basically, starting off with nothing, or with images and manipulating them. The way we did it, everything was actual photographed images. A lot of that stuff was shot through a microscope of chemical reactions, yeast growing, lots of weird things, by Peter Parks. We put it into a computer and collaged it, manipulated it. Meaning we digitally shaped it to fit with other images. But there was no computer-generated imagery at all.

I try to live my life where I end up at a point where I have no regrets. So I try to choose the road that I have the most passion on because then you can never really blame yourself for making the wrong choices. You can always say you're following your passion.

To me, watching a movie is like going to an amusement park. My worst fear is making a film that people don't think is a good ride.

The only way I know as a director is to figure out what the film is about. And out of the theme and the sense of what the film is about, all those decisions start to make sense. But to find that truth within it, you have to limit your possibilities and limit your choices. That's where this visual language grows out of.
