As much as I love acoustic Neil Young - and I do deeply - I may be more passionate about the electric. Luckily it's not a contest, and we never have to make that choice. But Neil Young on an electric guitar - I feel like I've never seen or heard anything like it.

Every film deserves its own unique look.

I had very strong feelings, so the chance to make a film that deals in an imaginative way with stuff you care tremendously about is a real high. It's a really amazing thing to be able to do.

I love doing fiction. I love doing performance films and I love doing documentaries that don't have music. I love to shoot and I love to shoot things I'm enthusiastic about.

I felt from time to time that shooting live music is the most purely cinematic thing you can do. Ideally, the cinema is becoming one with the music. There is little artifice involved. There's no acting. I love it.

Documentaries - my God, there is so much going on in our country and in the world today that every time you open the newspaper or turn on the radio or watch the news on TV there is another documentary subject. We're getting the headlines for a second, shaped by corporate delivery most of the time, but what's really the story there?

Extraordinary people are the Green Berets and the Navy Seals and the Olympic athletes - these are the ones who can face these extraordinary physical challenges and be triumphant.
