Why do people go to the cinema? What takes them into a darkened room where, for two hours, they watch the play of shadows on a sheet? The search for entertainment? The need for a kind of drug? All over the world there are, indeed, entertainment firms and organisations which exploit cinema and television and spectacles of many other kinds. Our starting-point, however, should not be there, but in the essential principles of cinema, which have to do with the human need to master and know the world. I think that what a person normally goes to the cinema for is time: for time lost or spent or not yet had. He goes there for living experience; for cinema, like no other art, widens, enhances and concentrates a person’s experience—and not only enhances it but makes it longer, significantly longer. That is the power of cinema: ‘stars’, story-lines and entertainment have nothing to do with it.
