This movie is an 1999 american film called "Fight Club". This film is directed by David Fincher (who direct a several good movies like "Social Network", "Se7en" and "The Girl With Dragoon Tattoo") and stars Edward Norton, Brad Pitt, Helena Bonham Carter.
Fight Club is about an "everyman" (Norton) who has a white-collar Job and he is very dissatisfied whit his life, with his job, his boss, and all the people who is around him. His way to scape, to sublimate all bad thing in his life he fall in all thing that belongs to a capitalist and consumist society. He has to buy always new furniture to feels well with himself.
This everyman suffers from insomnia (like a lot of people today who have headache or depress), and his doctro refuses to give him medication and advises him to visit a support group to see more severe suffering. Strangely he becomes addicted to attending this support grupos because he finds an emotional release that relivier his insomnia. He become impostor in several support groups but he find another impostor, Marla Singer (Bonham Carter), who disturbs him, so he negotiates with her to avoid the same groups.
After the mysterius destroy of his apartament, Norton calls Tyler Durden (Pitt), a soap salesman whom met in a business trip, and thet meet at a bar. In a conversation about consumerism provoke a conscious and a deliberate fight, which liberate the "everyman" so they start to fight all night outside that bar. This fight attract a lot men and they start to fight in the bar`s basement where form a "fight club"
I am not going to write more, because you have to see it, this movie has many changes in the plot. But I think that "fight club" is an intersting movie which deals about consumist society's subjective consecuence and psicology desease. And a way to scape ir and subvert it.
