In 1973, I was shown a graphic of how dependent the United States was on nonrenewable resources like oil and coal and that little was being done to change that. It seemed irrefutable that we needed a change in direction or we'd be paying a huge price down the road. That's when I made a commitment to become a political activist.

I'm interested in that thing that happens where there's a breaking point for some people and not for others. You go through such hardship, things that are almost impossibly difficult, and there's no sign that it's going to get any better, and that's the point when people quit. But some don't.

If you can do more, you should.

I don't think about when it's going to stop and what you do before it stops. You just keep moving.

Hollywood was not a place I dreamed of getting to. I never could take seriously the obsession people have about being a celebrity or getting to Hollywood - I was born next door.

As a director, I wouldn't like me as an actor. As an actor, I wouldn't like me as a director.

Filmgoers are starved for new ideas, voices and visions.
