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?

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 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.

Classical scores go up and down; they're kind of hysterical in a way. And movie scores are much more - they just drive and move forward, and they build and can't go up and down at that same speed. It's a big job to turn that into something that pushes the movie along.

I think people are people and, if their feelings are truthful, they can connect. It doesn't matter if you're an aging, 50-something wrestler at the end of his career, or an ambitious, 20-something ballet dancer.

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.

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.
