I do not make films which are prescriptive, and I do not make films that are conclusive. You do not walk out of my films with a clear feeling about what is right and wrong. They're ambivalent. You walk away with work to do. My films are a sort of investigation. They ask questions . . .. Sometimes I hear that some [Hollywood] studio is interested in me. Then they discover that this is the guy who works with no script, that there is no casting discussion, no interference, that I have the final cut, and that does it.
