The Firm is a 1989 British made-for-television drama film directed by Alan Clarke and written by Al Hunter Ashton for the BBC. It stars Gary Oldman, Lesley Manville, Phil Davis, Charles Lawson and Steve McFadden in his acting debut. The film is based on the activities of the Inter City Firm (billed as the "Inter City Crew") football firm of West Ham United during the 1970s and 1980s.

The film, which courted controversy on release, has come to be regarded among the finest films on the subject of football hooliganism. It is notable for having almost no musical score or diegetic music, save for Dean Martin's rendition of "That's Amore" over the opening titles. Oldman's performance has been hailed as one of the greatest of his career.
