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.

I've always played down the drama in my films. In my main scenes, there's never an opportunity for an actor to let go of everything he's got inside. I always try to tone down the acting, because my stories demand it, to the point where I might change a script so that an actor has no opportunity to come out well.

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.

A director is a man, therefore he has ideas; he is also an artist, therefore he has imagination. Whether they are good or bad, it seems to me that I have an abundance of stories to tell. And the things I see, the things that happen to me, continually renew the supply.

Reality has a quality of freedom about it that is hard to explain.

A scene has to have a rhythm of its own, a structure of its own.

In Blow-up I used my head instinctively!
