The way you really find out about the performer's seriousness about the cause is how long they stay with it when the spotlight gets turned off. You see a lot of celebrities switch gears. They go from the environment to animal rights to obesity or whatever. That I don't have a lot of respect for.

What we are living with is the result of human choices and it can be changed by making better, wiser choices.

Between 18 and 19 years old [in the 1950s] I came to Paris. I studied art. And that experience really did change my life. I was living hand to mouth. I walked everywhere. I thought, this city is incredible but you really have to experience it by walking it.

I've been able to carve out spaces for myself. At Sundance, I'm in the mountains - my property is private. I get on a horse and ride for three, four hours. Sometimes five. I get lost. But when I'm in, I'm in.

I'm not a facelift person. I am what I am.

The entertainment person gets a certain credibility, and the politician gets a certain notoriety. I'm against it.

I've always wanted to try new things because it's exciting and it keeps you active and alive.
