The amount of preparation I saw from someone like [David] Fincher, and how aware he is of everybody else's job on the set, and how much respect he has for every aspect of the film, and every aspect of the frame - that's the type of actor I am now; it's not the type of actor I was then. But without understanding his process, and then coming to learn it later on, I would never be the actor I am now.
