I think that it's fear. The musicians themselves don't seem to know enough about why they're in the positions they're in, so they're afraid to lose those positions. If you're 22 years old and you can't believe you're even in the position to have a career making music, the first thing you're going to think is: Maintain. Don't lose it. And that's precisely what causes you to lose everything.

Another thing that really excites me: I'd like to do multiple versions of the same film.

I suppose I could try to be some avant-garde artist if I wanted to, but that doesn't interest me as much.

My working life is me doing what I want to do. This is that. I've made movies that people don't go to see.

I think '60s are appealing to creative people, because it seemed to be a time of endless possibilities, when the boundaries of what could be considered popular culture were being expanded almost by the week. It doesn't feel like that anymore. At times, I wish it were so. Radio is a perfect example; good God, I mean, back then the most interesting songs were also hits, and that's just not true anymore. It hasn't been true in a long time.

The great thing about the business is how Darwinian it is. We have to swim or die - if you are found wanting over a period of time, you've either got to change what you're doing or find something else to do.

I'm always a little unnerved when I see a show that's set in the past that implies in any way that things were nicer then.
