Despite the film's realism - dozens of former hooligans were recruited as consultants and extras for effect - Football Factory's writer and director Nick Love does not believe young football fans will turn to violence after seeing it.
"You've got to question the sanity of a person who goes out for fights just because he's seen a film about it. I don't think it is that powerful. I'm absolutely amazed it has caused so much controversy. The film is more about working-class male culture, emotional violence and tribalism.
"It has a moral - the lead character gets half beaten to death and another goes to jail. There are just five minutes of violence in an hour and-a-half-long film."
Frank Harper, who plays one of the senior members of the firm in the film, said: "I don't think it glamorises football violence. Just look at what happens to the characters in the film. It's just a voyeuristic view of a sub-culture."
Last week a gang of hooligans were jailed for orchestrating "the battle of Maze Hill" between Charlton and Southampton fans two years ago.
