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 soap salesman Tyler Durden (Pitt), and becomes embroiled in a relationship with an impoverished but beguilingly attractive woman, Marla Singer (Bonham Carter).

Palahniuk's novel was optioned by Fox 2000 Pictures producer Laura Ziskin, who hired Jim Uhls to write the film adaptation. Fincher was selected because of his enthusiasm for the story. He developed the script with Uhls and sought screenwriting advice from the cast and others in the film industry. It was filmed in and around Los Angeles from July to December 1998. He and the cast compared the film to Rebel Without a Cause (1955) and The Graduate (1967), with a theme of conflict between Generation X and the value system of advertising.Studio executives did not like the film, and they restructured Fincher's intended marketing campaign to try to reduce anticipated losses. Fight Club premiered at the 56th Venice International Film Festival on September 10, 1999, and was released in the United States on

October 15, 1999 by 20th Century Fox. The film failed to meet the studio's expectations at the box office and received polarized reactions from critics. It was ranked as one of the most controversial and talked-about films of the 1990s. However, Fight Club later found commercial success with its home video release, establishing it as a cult classic and causing media to revisit the film. In 2009, on its tenth anniversary, The New York Times dubbed it the "defining cult movie of our time."
