"I have some radical theories about the difference between acting on stage and acting in front of the camera. [...] In a play the focal point – and the goal at all times – is to deprive the actor of dependence on his director, because the director is useless once the curtain rises. In the cinema it's the other way around. At the really important moment, it is the director who finds himself alone, with his reels, at the time of the final cut. [...] I don't think we can talk about a real performance of actors during filming. There are only repetitions, it's mechanical, fragmentary, because you can always redo it over and over again.
