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.

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.

Also expressionistic filmmaking - making the audience feel like they were inside the characters' heads. And so we create all these different types of techniques to put the audience there.

Now there is so much expertise and brainpower it's hard to be at the cutting edge of what's cool and not do something that's totally geeky.

I was a TV junkie as a kid. I am the Sesame Street generation.

It would be nice to make a movie that other people want to make, because every one of these movies, I basically have to find the only company in the world that's willing to make it, and it's always a big challenge. I end up spending a tremendous amount of energy and time trying to get money to make these movies and it's exhausting.

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.
