In theatre, there`s the director, the writer, and below them the actor. In film, it`s the actors who are most important. That goes against the grain for me. It`s been amazing for me to see the self-confidence of actors who insist on having control, because it`s going to be their faces 20ft high in the posters. I`ve been shocked by film actors - 25 and under - having such confidence and cockiness to rewrite a scene. My background is more about the director being in control. It`s all about yielding. It`s an oddly submissive relationship in which you`re moulded, Pygmalion-style.
