At the beginning of each movie scene, Steven Spielberg finds himself surrounded by enormous uncertainty. “Every time I start a new scene, I’m nervous,” he explains. “I don’t know what I’m gonna think of hearing the lines, I don’t know what I’m gonna tell the actors, I don’t know where I’m gonna put the camera.”30 Placed in the same situation, others might panic, but Spielberg describes it as “the greatest feeling in the world.” He knows that only conditions of tremendous uncertainty bring out his creative best.
