I don't make films that are easy to market, unfortunately. I think that 'Pi' was the easiest one, because we had that symbol to stick up everywhere, so that was a good gimmick, and created a good mystery, and we didn't have to do huge scale.

I was always writing about the connection between man and nature. I grew up in a neighborhood that was right on the beach, but the beach was not like a beach you would imagine - there was a lot of pollution. And the most magical thing to me as a kid was sea glass, so I wrote about that a lot.

I think video games and that stuff should be as violent as possible, but age-appropriate. It should be realistic. When it's not realistic you run into kids running around shooting people and not realizing the consequences.

Film is a great tool to play with time, going back and forth through time, or speeding time up and slowing it down and do stuff like that. That's something you can't experience in real life that you can experience on film, and it takes you to a different place.

People have been screaming about the end of times forever, it's always the end of times. But there's just so much evidence that the world is changing so radically right now. How much can the world take?

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.
