I've never had access to another person's art and work or, particularly, someone who is as prolific and was able to externalize his interior world as deeply as Kurt [Cobain] could.

When I grew up, we had no babysitters and nobody every observed us. People don't parent like that today. They're very hands-on; kids are constantly being supervised.

I try and make non-fiction films that feel like fiction, so I'm always looking for the subtext and that's what really excites me.

Sometimes, you chase the moment and you can never catch it. Films take so long to make that you can never anticipate what the cultural landscape will be when the film enters the world.

You can't divorce yourself from your own life experiences.

Every second counts. We are only on this earth for a short amount of time, and we get to decide how we want to use that time. And if one thinks that the purpose of life is to leave the world in just a little bit better place than we found it, it's hard to think of anyone who has contributed more than Jane Goodall.

I have three children, and they have never spent a minute unsupervised in their lives. My generation overcompensated like mad. I'm not even joking, every kid on my street [growing up] was molested. My kids would not have had an opportunity to molested, because they've never been alone, which is going to create a whole set of problems.
