I'd been influenced by reading books on art and colonies that existed in Paris and places like that and so when I came to Europe I came to France and I had very little money, and I had to live low and stayed in a bohemian section of Paris with a lot of other students, who were from medical school, science school and art school. We all lived in a kind of communal way and I was challenged politically, because I didn't have a clue and they would ask me questions about the Algerian War, which was very big in France in the late '50s.

You should prepare when you go to a public event to be public. That's when I will sign autographs. But not when you're going about your normal business.

Television tells us only the things it wants to. It still feeds us heroes, it still offers villains. And even though we know better than to always trust it, we still watch.

Politics right now is in a very dark place, and I think the only place for me is to do what I do - make films, create art, watch it as it evolves. Right now it's like Humpty Dumpty sitting on a wall, and a great fall is happening. The behavior seems to be really dumb.

All my life I've been dogged by guilt because I feel there is this difference between the way I look and the way I feel inside.

The meter is ticking [particularly in the face of climate change], so you've got to get to as much as you can as fast as you can. I grew up with 'This Land Is Our Land,' and public land doesn't belong to that administration or this one. We want our kids to grow up with real natural places, not just photos of them.

I don't think you can ever return, really.
