I had a mild case of polio - not enough to put me in an iron lung, but enough to keep me bedridden for weeks. As I came out of it, my mom wanted to do something for me. She realized that, growing up in the city, I'd missed out on a lot of nature.

All of the films that I've made are about the country I live in and grew up in... And I think if you're going to put an artist's eye to it, you're going to put a critical eye to it. I've always been interested in the gray area that exists between the black and white, or the red and blue, and that's where complexity lies.

I was never a good student. I had to be dragged into kindergarten. It was hard to sit and listen to somebody talk. I wanted to be out, educated by experience and adventure, and I didn't know how to express that.

I think a lot of people thought my career started with Butch Cassidy.
