Fight Club is a 1999 film directed by David Fincher about a nameless narrator who suffers from insomnia. He begins attending support groups for various illnesses despite not being sick. He meets Marla Singer and Tyler Durden, and they form an underground fighting club in secret locations that grows into a larger anti-consumerist organization called Project Mayhem. The narrator comes to realize he has dissociative identity disorder and that Tyler is a hallucination stemming from his own psyche. The film was controversial upon release due to its depictions of violence and anarchism.
