You have these relationships with people that you care about, but I also try to stick to my job as filmmaker and be fair and truthful about what I saw and my experience of the people, hopefully informed by a deep understanding of them.

I focus on a lot of women's issues.

What I'm documenting can be hard to distill, because it's all around us like the air we breathe. I often need to go to a place where I can capture extreme moments.

All my film ideas and subjects have come from photography.

I've often looked at the extremes as a way to shed light on the mainstream. Even though everybody says, "Money doesn't buy you happiness," I don't think that that's the principle by which people live. If you talk to kids and ask them what they want to be when they grow up, they say, "Rich and famous," but being rich and famous is not a job.

I'm also looking for the psychological elements that fuel commodity culture. For example, if we imbue girls with deep insecurity about their bodies through images of an impossible ideal, we create a really vulnerable and avid consumer. If somebody feels that they're not OK without a certain product, you have a very deep and loyal market that will come back to the product again and again. Sometimes, this process is both rational and irrational.
