Don't talk like one of them. You're not! Even if you'd like to be. To them, you're just a freak, like me! They need you right now, but when they don't, they'll cast you out, like a leper! You see, their morals, their code, it's a bad joke. Dropped at the first sign of trouble. They're only as good as the world allows them to be. I'll show you. When the chips are down, these... these civilized people, they'll eat each other. See, I'm not a monster. I'm just ahead of the curve. -The Joker
Christopher NolanIt's very important that a film that intends to play tricks on the audience... has to play fair with the audience. For me, any time you're going to have a reveal in the film, it's essential that it have been shown to the audience as much as possible. What that means is that some people are going to figure it out very early on. Other people not til the end. Everybody watches the film differently.
Christopher NolanI always find myself gravitating to the analogy of a maze. Think of film noir and if you picture the story as a maze, you don't want to be hanging above the maze watching the characters make the wrong choices because it's frustrating. You actually want to be in the maze with them, making the turns at their side, that keeps it more exciting...I quite like to be in that maze.
