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.

Film is simply the most complex way you can express yourself

Pornography, it seems to me, is no different from war films or propaganda films in that it tries to make the visceral, horrific, or transgressive elements of life consumable.

It's unbearable when someone changes around you. Just imagine that your life partner changes, then it is difficult to cope with. Or your mother. Or your father. They were strong and now they're like a baby - it's not so funny.

Writers and filmakers, that is, people who describe the world, suffer from an occupational disease. They never experience moments in life quite spontaneously. You always look at yourself from the outside. Even as a child I always observed myself and the world. I believe that everyone who chooses this path in any way, who chooses to be a describer of life, suffers from this condition. It's like a mental obsession. It can be a great pity too. It robs you of a certain joy in spontaneity.

There are really two types of laughter on the part of the spectator. There is the laughter of recognition - which means seeing things you're familiar with and laughing at yourself. But there's also hysterical laughter - a way of dealing with the things we see that upset us.

To decide to film a movie again shot by shot, you must be masochistic to a certain degree because it is a much greater challenge.
