When I'm sure I have a story, I call my collaborators and we begin to discuss it. And we conduct studies of certain subjects to make sure of our terrain. Then, finally, in the last month or two, I write the story.

When I am shooting a film I never think of how I want to shoot something; I simply shoot it.

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 struggle for life is not only the material and economic one. Comfort is no protection from anxiety.

I may film scenes I had no intention of filming; things suggest themselves on location, and we improvise. I try not to think about it too much. Then, in the cutting room, I take the film and start to put it together, and only then do I begin to get an idea of what it is about.

It isn't easy to understand the lives of people different from your own.

I don't know whether I am ever bored. I never look at myself.
