I write scripts by myself. It's not for everybody. It's someone's personal work. I need to be in love with the subject.

It's always more interesting and more difficult to make something positive than negative. To be negative is very easy.

If you make the right choice in casting, your work is nearly done already. You don't have to spend a lot of time directing the actors, because they're so well suited to the parts.

It's always been pretty easy for me to exercise my imagination. The other part of the brain, the one that does mathematics, is a nightmare for me. It doesn't work at all.

Each time, I try to find a family of interesting faces. I follow the tradition of films from the 40s - at this time, there were so many interesting faces in France. I often work with the same because there are not thousands and thousands in France. I'm looking for interesting faces and characters actors, and it's not for everybody.

I'm very slow, and I do everything myself. I remember I spent three days to change the size of something I had sketched because I felt it was too small.

I think we're entering a new period of filmmaking that's analogous to switching from black-and-white to color, or from silent to sound. The medium is completely flexible, and it's not bound by anything. If you imagine something, you can do it.
