Little people have changed from the 1970s to now.

Technology changes so much that it has forced me to adapt.

Most of my work is okay to look at on a TV screen or a flat screen, but this is actually much better in a theatre.

I always chose talkative people. And Viva, who was my first wife - we started making films together because she was extraordinarily creative. I was drawn to those people who tended to talk or act differently. The nice thing about using your friends as actors is they trust you. I wouldn't use footage of people that was destructive to them.

I don't see my work as being all that personal. I've used my personal experience in the world, of course, or at least my way of looking at the world. But I think that's changed as I've gotten older.

People have a tendency to think I was part of Warhol's Factory - I never was. I've always been independent.
