Well, the first thing I had to do was to read a lot. First of all, about education... and looking at education from the Middle Ages right through to the 20th Century. The second major area was country life in the 19th Century, which I don't know much about these days.

In general, in all my films, I choose to create a certain mistrust, rather than claiming that what I'm showing onscreen is an accurate reproduction of reality. I want people to question what they are seeing onscreen. In the same way as I used the narrator, I also used black and white, because it creates a distance toward what's being seen. I see the film as an artifact rather than a reliable reconstruction of a reality that we cannot know.

A feature film is twenty-four lies per second.

What I like are films that take me seriously, that don't treat me as more stupid than I am.

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.

What we're doing for another person is more important than what we're feeling for them.

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.
