The Football Factory (2004)

The Football Factory" focuses on two different groups of English football supporters -- the Headhunters, who support Chelsea, and the Bushwhackers, who support Millwall. Throughout the movie, the Headhunters fight with other English groups such as those supporting Tottenham Hotspur, Liverpool, and Stoke City.
There is an early homage scene to Goodfellas where Billy scares Zeberdee at a bar because Zeberdee said something derogatory about him in jest.
When the draw is made for the playoffs, Chelsea draws Millwall and then the violence really begins. Tommy Johnson has begun to question his morals and the morals of those around him. Tommy's major conflict in the film stems from his inevitable aging. Although he loves his weekend fights,he knows he cannot continue this life style forever.
When Tommy goes home with a girl, it ends up being a Millwall supporter's daughter. and Tommy has to whack the brother with a cricket bat to get away. For the rest of the movie Tommy tries to evade the Millwall gang who are want to get even.
In the end, Tommy is beaten with a brick, but he decides that fighting alongside his fellow men is "worth it", and stumbles to the bar to reunite with his friends. He learns that psychopath Billy Bright has been sent to prison and the movies final moment witnesses the death of Zeberdee at the hands of a drug-dealer.
Tommy's decision at the end, that hanging with his friends and the adrenaline rush he gets from the fighting may be a metaphor for the world of sports in general. The only difference is the professionals get paid. But for all the others, who got out and risk their bodies to "play" sports and hang with their friends, it isn't really all that different from the hooligans portrayed in this movie who are playing a game of their own.
This was not really a movie about soccer. It is a movie like Green Street Hooligans, about the violent hooligan culture that uses soccer as an excuse to play a game of their own. With these groups it is the fighting and violence that is the "thing", not really the soccer. The groups act and think like the characters in a Clockwork Orange. The movie was interesting, honest and frightening.
