I don't think I'm morbid by nature. Serious writers have always written about serious subjects. Lighthearted material doesn't appeal to me, and I don't read it. I think I'm a realist, with a realistic sensibility of history and the tragedy of history.
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.
