Among a great many other things that chess teaches you is to control the initial excitement you feel when you see something that looks good. It trains you to think before grabbing, and to think just as objectively when you're in trouble. When you're making a film you have to make most of your decisions on the run, and there is a tendency to always shoot from the hip. It takes more discipline than you might imagine, to think, even for thirty seconds, in the noisy, confusing, high-pressure atmosphere of a film set. But a few seconds' thought can often prevent a serious mistake being made about something that looks good at first glance. With respect to films, chess is more useful in preventing you from making mistakes than giving you ideas. Ideas come spontaneously and the discipline required to evaluate and put them to use tends to be the real work.
