What is Fight Club about?
Fight Club is an extremely complicated film, with different theories about what it is about. The protagonist, a depressed office worker with insomnia, meets a "soap maker" called Tyler Durden on a business trip, after this the plot thickens. It is clear that Tyler Durden is an alter ego caused by hallucinations from having insomnia. This possibility is posed during the end of the film before Tyler blows up city buildings. The existence of Tyler is also questioned when Marla comes to see Edward Norton's character but shortly leaves in anger after Norton's character states that "Tyler isn't here" whilst holding a bottle of alcohol.
