My generation is having its midlife crisis in its 20s.

Basically, I think 21st century conservation is moving toward preserving ecosystems by dealing with the needs of people.

When I was about 16 or 17, I had a teacher who took a group of us to the National Theater in Washington, D.C., and I saw Ian McKellen do his one-man show - I think it was called Acting Shakespeare - and it completely bombed me; it put the zap on my brain in a big way.

I'm pretty busy in my life and I'm very aware of what it takes to direct a movie. It takes a lot out of you; it takes a lot out of the rest of your life, from other people in your life. I don't lie around hungering for that consumption very often.

But work that's got real substance does make people feel, "There's someone else out there who relates to my experience, or who just helped me understand my own experience a little bit better." And I think that's still got enormous value.

I don't flatter myself - I'm not a scientist, I'm not a conservation expert.

I'm not particularly precious about the theatrical experience any more.
