Scum is a 1979 British drama film directed by Alan Clarke and starring Ray Winstone, Mick Ford, Julian Firth and John Blundell. The film portrays the brutality of life inside a British borstal. The script was originally filmed as a television play for the BBC's Play for Today series in 1977. However, due to the violence depicted, it was withdrawn from broadcast. Two years later, director Alan Clarke and scriptwriter Roy Minton remade it as a film, first shown on Channel 4 in 1983. By this time the borstal system had been reformed. The original TV version was eventually allowed to be aired eight years later in 1991.
The film tells the story of a young offender named Carlin as he arrives at the institution and his rise through violence and self-protection to the top of the inmates' pecking order, purely as a tool to survive. Beyond Carlin's individual storyline, the film also serves as an indictment of the borstal system's flaws with no attempt at rehabilitation. The warders and convicts alike are brutalised by the system. The film's controversy was derived from its graphic depiction of racism, extreme violence, rape, suicide, many fights and very strong language.
