Drama lives on conflict. If you're trying to deal with social issues seriously, there's no way of avoiding violence, which is so present in society.

It's a fact that people who are in a weakened position, whether physically or mentally, have this perception of the outer world as threatening. Everything that is unexpected or unknown is seen as a potential danger.

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

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.

It's much harder to write a script that involves two people in a single location than 20 people in 30 different locations.

Like every filmmaker, I make my films to reach the widest audience possible.

In German. I'm more sensitized to the details, to the emotions. In English, I wouldn't detect as much nuance.
