Green Street is a 2005 British-American independent drama film about football hooliganism. It was directed by Lexi Alexander and stars Elijah Wood and Charlie Hunnam. In the United Kingdom, it is called Green Street. In the United States, Australia and South Africa, the film is called Green Street Hooligans. In other countries, it is called Football Hooligans or just Hooligans. In the film, an American college student falls in with a violent West Ham football firm (the Green Street Elite) run by his brother-in-law's younger brother and is morally transformed by their commitment to each other.
The story was developed by Lexi Alexander, based on her own experience in her brother's firm. Unwilling to shoot the film with German speaking actors, Lexi decided to adapt the heart of the story into the world of English hooliganism. While researching the subject on British internet forums, she came across a self-described hooligan who urged her to contact author Dougie Brimson. Brimson later admitted that he had been the hooligan who had initially made contact and had used a false identity to sound out Alexander and establish both her identity and her credibility.
Brimson wrote the initial script but Alexander later recruited another writer, Josh Shelov, to assist with structure and plot, while Brimson offered technical advice. However, little of his rewrite made the final cut on account of Shelov's lack of understanding of both football and the hooligan culture.
