For me, it's always difficult when a historical film claims to depict or represent a reality that none of us can know, that is always different. It's always the case. We never know what happened then. So my approach with the narrator is to question that, to leave that open, to underline the fact that this is uncertain.

Even the most elitist director or author who claims that he doesn't care if his works are seen or not, then I have to think that he's either a liar or a hypocrite.

Every form of anti-Semitism, every form of xenophobia plays on the fear of the unknown, and unfortunately there are all too many politicians who know how to manipulate that. The dumber people are, the more they feel the need for a broad set of shoulders they can lay their head against.

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.

I've never let producers tell me what to do. Even when I was making television, I always did what I wanted to do, and if I couldn't, I didn't do it. It was a freedom that, these days, young directors starting out don't have.

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.
