Fight Club is a 1999 American film directed by David Fincher and starring Brad Pitt, Edward Norton, and Helena Bonham Carter. It is based on the 1996 novel by Chuck Palahniuk. Norton plays the unnamed narrator, who is discontented with his white-collar job. He forms a "fight club" with a soap salesman, Tyler Durden (Pitt), and becomes embroiled with an impoverished but beguiling woman, Marla Singer (Bonham Carter).

The unnamed narrator is an insomniac dissatisfied with his job and lifestyle. As a form of therapy, he attends support groups for problems he does not have, such as alcoholism and testicular cancer. Here, he finds emotional release in expressions of vulnerability, until he encounters another impostor, Marla Singer. After a confrontation, the two agree to attend different groups.
