Fight Club is a 1996 novel by Chuck Palahniuk. It was Palahniuk's first published novel, and follows the experiences of an unnamed protagonist struggling with insomnia. The protagonist finds relief by impersonating a seriously ill person in several support groups, after his doctor remarks that insomnia is not "real suffering" and that he should find out what it is really like to suffer. The protagonist then meets a mysterious man named Tyler Durden and establishes an underground fighting club as radical psychotherapy. In 1999, director David Fincher adapted the novel into a film of the same name, starring Brad Pitt and Edward Norton. The film acquired a cult following despite underperforming financially, and heightened the profile of the novel. Source: Wikipedia (en)
