I had in mind a case close to my family, friends of my parents, who seemed to be the perfect bourgeois family, and a young boy, who when he was 17, committed suicide. It was such a shock. The parents didn't understand. Nobody understood why he did that. Everybody was exploring his life, trying to understand what the problem was. Everybody had a feeling that this guy had the perfect life: he was beautiful, he was clever... but he did that. I had that in mind, about Isabelle in Young and Beautiful, for the parents to see adolescents like aliens.

It was not easy when I was a teenager. But today, with the new technology, with the Internet, everybody can do prostitution with two clicks. During the period of Belle du Jour, it was a very strong decision to go into the profession, but now, if you need a little bit money, you go on a website and you say, "Can I have 50 dollars?" It's easy! I wanted to show these facilities.

Speaking with many young people, they act like their virginity is something you have to turn the page very quickly on. "It's done."

Actually, for everybody, having sex the first time is never a good time. It's always a disaster.

There is a kind of syndrome of girls who want to dirty themselves. They have the power. They control everything.

I didn't want to make Young and Beautiful as very dramatic movie . In a certain way, I wanted to do a girly film. I wanted to make something sweet, pink. With a boy it was too dramatic and too heavy. I had a lot of pleasure with the boys in In the House, I said, "This time I will do a film with girls."

I think, when you are the prostitute... you don't want to be coming.
