Women in prison film is a subgenre of exploitation film.
Their stories feature imprisoned women who are subjected to sexual and physical abuse, typically by sadistic female prison wardens. The genre also features many films in which imprisoned women engage in lesbian sex.
Perhaps the best explanation for women in prison films' notoriety is that it is a cinematized version of the "men's adventure" subgenre of pulp fiction. Nazis tormenting damsels in distress were perennial favourite subjects for the lurid, sub-pornographic covers of sensationalistic "true adventure" magazines such as Argosy in the 1950s and 1960s; the film seeks to be a more explicit version of the same sort of catfight sexual fantasy.
Women in prison films developed in the 1930s as melodramas. Young heroines were shown the way to a righteous life by way of the prison. Under the influence of pulp magazines and paperbacks, they became popular B movies in the 1950s.
The film that kicked off the genre in a new direction was Jesus Franco's 99 Women, which was a big box office success in the US in 1969. Since the 1970s they become a specialty product of pornography. Women in prison films have more to do with sexual fantasies than real prison life.
The most well-known examples of the women in prison film are perhaps Ilsa, She-Wolf of the SS and Jonathan Demme's Caged Heat. Actress Pam Grier starred in a number of films in the genre, such as Roger Corman's The Big Doll House, The Big Bird Cage, and Women in Cages. There is also the notorious Reform School Girls in 1986, with Wendy O Williams.
European cinema too had its share of the genre with titles like the Frauengefängnis (1975) and Sadomania (1981) by Jess Franco.
In Japanese cinema, Meiko Kaji starred in the Sasori (Scorpion) series of women in prison films, directed by Shunya Ito and adapted from manga.
A number of these films remain banned by the BBFC in the United Kingdom. Among them are Love Camp 7 (rejected in 2002) and Women in Cellblock 9 (rejected in 2004), on the grounds that they contain substantial scenes of sexual violence.
The lesbian theme in these films also seemingly influenced mainstream films as Chicago (2002) and Strangers with Candy (2006).
