When you see Fight Club, you'll have "front row seats for the theater of destruction."
Ostensibly a movie about underground ultimate fighting, Fight Club is actually an externalized psychodrama and the best illustration of the internal workings of an MPD (Multiple Personality Disorder) victim ever made.
Narrated by the wimpy antihero (Edward Norton), Fight Club begins as the savage Tyler Durden (Brad Pitt) forces a gun into his mouth. The rest of the movie is an extended flashback until the end, as the Narrator in a deadpan voice-over describes his life in a nightmarish first person rant.
The super-alienated Narrator works as a zombified analyst for a big car company. He suffers from insomnia, and a doctor, in a spoof of new age medicine, tells him to chew some valerian and get some rest.
Since his bean-counter job is to figure out how many customer deaths will warrant a product recall, he spends the rest of his time compulsively ordering home furnishings for his apartment.
