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.

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.

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.

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 never met Kurt Cobain, but I felt like I got to know him in a manner probably more intimate than anyone I've known outside of my family.

One thing about Kurt [Cobain] is before he was a musician, and before he was a rock star, he was an artist, and an artist with a capital A. What that means is that he had to create. It wasn't something that he chose to do - it chose him.

My documentaries have always been very much constructed in the spirit of dominant cinema. From the time I started making non-fiction, I was mainly interested in designing and creating documentaries like fiction, so it was a natural evolution to try and embark on doing a dramatic narrative.
