There's always this problem in society where people know they need these places for social peace, but the fundamentalists want to shut them down. Sometimes that's for economic reasons, because they want to build a supermarket there. The imam will hold a prayer and say let's get rid of the girls, but on the other hand they're all going there.

Sometimes the presence of a camera is like opening a door, because many people want what Andy Warhol called "15 minutes of fame." But prostitutes don't want that.

I don't aestheticize anything. I don't even use lights. The working girls do one thing all day: They make themselves pretty. That's their job and their money. In a way, I had the best makeup artists, hairdressers, and art designers in the world.

Whenever a man enters the realm of prostitutes he's always regarded as a possible customer. If you enter as a woman, you're regarded as somebody who could be in the same place. Being a man brings the perspective of flirtation.

You can become an alcoholic working in an office in Los Angeles. It's very easy to say because I do this shameful job I take drugs or drink, but the real reason prostitutes take drugs and drink is because prostitution is a party area. It's not about desperation, it's the surroundings.

I've made many documentaries, but prostitution was the hardest in terms of gaining the trust of the people being filmed.

On one hand, prostitutes don't struggle because it's simply their life. In Mexico and elsewhere, once they get out of these places [brothels] they have a pretty square life. In Bangladesh it's different because they live in the brothel, it's sort of a prison, but still there are two sides. When they think of their religion and their upbringing, they can be very moralistic. They're moralistic about giving blow jobs. On the other hand, they have an everyday life where there's no room for shame.
