For me, from the moment when the first, still unformed, idea comes into my head until the projection of the rushes, the process of making a film constitutes a single piece of work. I mean that I cannot become interested in anything, day or night, which is not that film. Let no one imagine that this is a romantic pose — on the contrary. I become relatively more lucid, more attentive, and almost feel as if I were intelligent and more ready to understand.
