Women in Cellblock 9 (Original title: Frauen für Zellenblock 9) is a 1977 Swiss exploitation action horror film written and directed by Jess Franco, and starring Karine Gambier. Its main theme is women in prison. Unlike most of Franco's work, this film remains banned in the United Kingdom due to large amounts of sexual violence, and as one of the lead actresses in many of the sex scenes was 16 at the time the film was made. The film was rejected by the British Board of Film Classification when submitted in 2004 and has since not been successfully appealed.
