It'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.
