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.

I spent about a year and a half doing technical post work on 'The Fountain'. Although I do like the process, I think my favorite part of filmmaking is the actors.

Unfortunately, when you're working in film, it's this huge machine, and you've got to get everyone right there, so you get kind of locked into things. I'm not sure where the artistry in film making is. It's usually that moment when you're on set and you're working with the actors. That's the time to play around, the moment of theater. And then you can shape things. But a lot of it is just managing stuff. It's upsetting because you get away from the core.

It's not that much of a difference. Basically, your job is the same as a film director. It's a triangle between creativity, money, and time. But they don't really change. You're ultimately trying to get the most creativity and time with the money that you have.

I think that there's an infinite amount of places where you can stick a camera. There's an infinite amount of choices of what could be going on. There's an infinite amount of places for so many things, so you have to figure out how to do your job.

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.

Casting ethnic characters is a very hard thing to do, but it's important. It's also interesting.
