As I do with most films, I try and find some music that you could use throughout, not just a sampling of lots of different artists.

It's easy to keep score at a football game because it's just how many times you get the ball over the goal. But, when you ask an audience to tell us how many times the invisible ball got over the invisible goal, and they go, "Well, it was 46," they're just making it up. So, if you're listening to that, as though you're actually listening to the score of a football game, you're misleading yourself.

Wong Kar-Wai is a really great inspiration. He's always referred to as the Jimi Hendrix of filmmaking.

I'd come into filmmaking as a painter so, for me, making 'Good Will Hunting' was experimental because I didn't know how to do it.

I was petrified because all my friends would be going to Washington, DC, to protest. I was sixteen, and I was like, "I don't think I'll be going with you guys," just because I was scared. Then you saw the news, and cops - not students in schools with guns - cops are killing sixteen year old protesters on the news. To me that was more horrifying, to have the authority figures actually killing people on the evening news, than to have another student firing a gun.

In rare cases, I've had music before I shot the movie. I think that for 'Good Will Hunting' I had an Elliot Smith record or a couple of them and I just somehow felt like the sound had something to it that reminded me of the story. So in that case there was music beforehand.

My department is to get actors to do stuff.
