My feeling, however, is that films that are open are more productive for the audience. The films that, if I'm in a cinema, and I'm watching a movie that answers all the questions that it raises, it's a film that bores me. In the same way, if I'm reading a book that doesn't leave me with questions, moving questions, that I feel confronted with, then for me it's a waste of time. I don't want to read a book that simply confirms what I already know.

The trouble is that when you read criticisms about the other films that I've made you get the impression that they're all about themes, or problems, or ideas. But those are actually things that develop out of characters, out of images and out of other things. These more abstract things develop while working on the material, and out of it. It's not a theoretical exercise from the outset.

There is just as much evil in all of us as there is good. We're all continuously guilty, even if we're not doing it intentionally to be evil. Here we are sitting in luxury hotels, living it up on the the backs of others in the third world. We all have a guilty conscience, but we do very little about it.

It could be Fascist, religious or political - it's always the same model that operates in these circumstances, and it's that which is the actuality of this film. Therefore, it's not specifically an explanation of German Fascism because that would be an impossible thing to do in any case.

Usually, when making a film, the surprises are negative surprises. You don't get what you wanted or what you hoped for. The only nice surprises are those that are offered to you by actors when they offer you these gifts, when they are better and give you more than what you had originally conceived. That doesn't happen every day on set, but if it happens a couple of times in the course of making a film, you can consider yourself very lucky.

Usually music is used to hide a film's problems.

My mother as a young girl went out with a young SS officer and she didn't really know what was going on - she just liked the uniform. When he told her about the things that he did, she was disgusted and broke up with him.
