In the Bengali language, there's not a real word for blow job. They call it "doing the ice cream."

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

Sometimes the presence of a camera is like opening a door.

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.

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.

La Zona is such a closed area, a dangerous, outlaw area. My time in the Zona was a time outside of society, almost out of the real world. And the girls there had such a sense of irony and sarcasm. They were also really interested in my film. They'd be like, "Thank God we live in Mexico, because our kind of prostitution has a heart. We wouldn't want to sit behind a glass cage or be sold by our own mothers. We have free will."
