One of the problems of the future world will be the use of leisure time. How will it be filled up? Maybe drugs will be distributed free of charge by the government.

The script is a starting point, not a fixed highway. I must look through the camera to see if what I've written on the page is right or not. In the script, you describe imagined scenes, but it's all suspended in mid-air. Often, an actor viewed against a wall or a landscape, or seen through a window, is much more eloquent than the lines you've given him. So then you take out the lines. This happens often to me and I end up saying what I want with a movement or a gesture.

I simply know what the actor's attitude should be and what he should say. He doesn't, because he can't see the relationship that begins to exist between his body and the other things in the scene.

A particular type of film emerged from World War Two, with the Italian neorealist school. It was perfectly right for its time, which was as exceptional as the reality around us. Our major interest focused on that and on how we could relate to it. Later, when the situation normalized and post-war life returned to what it had been in peacetime, it became important to see the intimate, interior consequences of all that had happened.

The script is simply a series of notes for the film.

I believe in the autobiographical concept only to the degree that I am able to put onto film all that's passing through my head at the moment of shooting.

It's obvious that I must explain what I want from an actor, but I don't want to discuss everything I ask him to do, because often my requests are completely instinctive and there are things I can't explain. It's like painting: You don't know why you use pink instead of blue. You simply feel that's how it should be - pink. Then the phone rings and you answer it. When you come back, you don't want pink anymore and you use blue - without knowing why. You can't help it; that's just the way it is.
