I like the saying: "The world is as you are." And I think films are as you are. That's why, although the frames of a film are always the same - the same number, in the same sequence, with the same sounds - every screening is different. THe difference is sometimes subtle but it's there. It depends on teh audience. THere is a circle that goes from the audience to the film and back. Each person is looking and thinking and feeling and coming up with his or her own sense of things. And it's probably different than what I fell in loe with.So you don't know how it's going to hit people. But if you thought about how it's going to hit people, or if it's going to hurt someone, or if it's going to do this or do that, then you would have to stop making films. You just do these things that you fell in love with, and you never know what's going to happen.
