I try to do nothing. I drink rosemary when I have a lot of work to do. People take coffee, they take speed, whatever. I take rosemary.

When I started I did not know I wanted to be a filmmaker. I started - I made a film. Then when I finished I said, Oh my god it's so beautiful - I should be a filmmaker!

I just didn't see films when I was young. I was stupid and naïve. Maybe I wouldn't have made films if I had seen lots of others; maybe it would have stopped me.

Good cinema is good cinema. It makes you feel like you need to work. Just yesterday I saw a good film, but even if I'd seen a bad one, I'd feel, "Oh my god, what a bad job, I can do better."

I see all these students, and I admire them - they're trying to learn something, they go to school, they do film school, they go on shoots, they help. I'm sure they learn a lot, and some of them, it makes them aware of what they wish to do. I was - that's the way I was - autodidact.

I wanted to catch the problem of consumption, waste, poor people eating what we throw away, which is a big subject. But I didn't want to become a sociologue, an ethnographe, a serious thinker. I thought I should be free, even in a documentary which has a very serious subject.

When I started my first film, there were three women directors in France. Their films were OK, but I was different. It's like when you start to jump and you put the pole very high - you have to jump very high. I thought, I have to use cinema as a language.
