If a director says he doesn't care how many people see his films at all, I simply don't believe him. Otherwise why would he bother to make the film? The only explanation would be that it would be an act of masturbation. I think that every creator is looking for a receptor. He's looking for an audience. There are two parts of the equation: a creator and, necessarily, the receiver of the work. It's the same thing for a painter who wants his paintings to be seen.

I want to be able to control things and that's very difficult to do if you're not 100% in a particular language. It makes you uncertain and it makes you nervous.

I'm not someone who enjoys long talks, long rehearsals. I'm very technical: I tell my actors, you come in, you sit down, you pick up a coffee, you look here, you say the line. We try it with the cameras rolling, and if it doesn't work, we adjust it until it does. It's very simple.

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.

I'm far more relaxed with German. I'm a control freak. I like to know exactly who's saying and doing what.

It's impossible to consider living without ideals. However, when ideas lead to ideology, that's a very dangerous thing. Ideology then leads to creating the image of an enemy, and it leads to the murder and massacre that we've seen since the beginning of time.

It's difficult because you can't generalise about these things. But in essence, you deal with children as simply as you deal with actors - you have to show a certain sort of respect. You deal with them lovingly and protect them, but if you protect them enough then they're open to engage with what you want to do with them.
