"When you make a movie, it takes a few days just to get used to the crew, because it is like getting undressed in front of fifty people. Once you're accustomed to them, the presence of even one other person on set is discordant and tends to produce self-consciousness in the actors, and certainly in itself". He also told biographer Michel Ciment: "It's invariably because the actors don't know their lines, or don't know them well enough. An actor can only do one thing at a time, and when he learned his lines only well enough to say them while he's thinking about them, he will always have trouble as soon as he has to work on the emotions of the scene or find camera marks. In a strong emotional scene, it is always best to be able to shoot in complete takes to allow the actor a continuity of emotion, and it is rare for most actors to reach their peak more than once or twice. There are, occasionally, scenes which benefit from extra takes, but even then, I'm not sure that the early takes aren't just glorified rehearsals with the adding adrenaline of film running through the camera."
