I consider all my films an experiment, at least in my mind.

It's more enjoyable to shoot in a studio on a single location with two actors... if they are good.

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.

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.

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.

Film is the manipulative medium par excellence. When you think back on the history of film and the 20th century, you see the propaganda that's been made. So there are moral demands on the director to treat the spectators as seriously as he or she takes himself and not to see them merely as victims that can be manipulated to whatever ends they have.

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