"People are always asking me if I know Tyler Durden." David Fincher is a tricksy little fellow. In Fight Club, he decides to give away the entire twist of the movie in the very first line -- but you only realize that after you've watched the whole thing. When Ed Norton comments on how people always ask him if he knows Tyler Durden, its a sly wink at their shared identity, and it's infuriating when you realize exactly how many clues you were given throughout the film that were disguised as seemingly innocuous comments. The twist is expertly crafted by a master filmmaker right from the first line of the movie.
