Fight Club is a cult classic that has transcended generations. Brad Pitt and Ed Norton star as the chaotic duo who start the infamous basement Fight Club. Norton plays the main character "The Narrator" and Pitt plays Tyler Durden. The end twist definitely lives up to the hype, but how did it happen?
In the end, it's revealed that Tyler Durden and The Narrator are one of the same. Durden was just a figment of The Narrator's imagination and projection of an alter ego. All of the scenes of them together were part of The Narrator's imagination, especially when they were alone.
