Nunsploitation is a subgenre of exploitation film which had its peak in Europe in the 1970s. These films typically involve Christian nuns living in convents during the Middle Ages. The main conflict of the story is usually of a religious or sexual nature, such as religious oppression or sexual suppression due to living in celibacy. The Inquisition is another common theme. These films, although often seen as pure exploitation films, often contain criticism against religion in general and the Catholic church in particular. Indeed, some protagonist dialogue voiced feminist consciousness and rejection of their subordinated social role. Many of these films were made in countries where the Catholic Church is influential, such as Italy and Spain. One atypical example of the genre, however, is Killer Nun (Suor Omicidi), set in, then, present-day Italy (1978).
Nunsploitation, along with nazisploitation, is a subgenre that ran a parallel course alongside women in prison films in the 1970s and 1980s. As with prison films, they are set in isolated, fortress-like convents where the all-female population turns to lesbianism and perversity. The element of religious guilt allows for lurid depictions of "mortifying the flesh" such as self-flagellation and painful, masochistic rituals. The mother superior is usually a cruel and corrupt warden-like martinet who enforces strict discipline (more opportunities for whippings and medieval-style punishments) and often lusts after her female charges. An equally sadistic and lecherous priest is often included to add an element of masculine menace to the story.
Some segments from the Scandinavian silent film Häxan (1922) may be seen as a precursor for this genre. A more recent act of nunsploitation in a film is in Robert Rodriguez' Machete (2010), where Lindsay Lohan portrays a gun-toting nun.
Among other examples of exploitation cinema in Europe over the last sixty years, nunsploitation genre movies are discussed in Mendik and Mathij's recent overview volume on this general trend within regional cinema genres, cultures, and audience consumption. Chris Fujiwara wrote a detailed piece discussing examples of the genre such as Killer Nun (1978), The Nun and the Devil (1973) and Flavia the Heretic (1974), in Hermenaut, a USA pop culture journal.
Historical basis 
Some films, such as the X-rated The Devils, based on a book by Aldous Huxley and directed by Ken Russell, have some basis in fact. Huxley based his original historical account, The Devils of Loudun, on a reported case of mass hysteria and demonic possession that allegedly took place at a French convent in the seventeenth century. Given that the genre was the product of the sixties and seventies, with an occasional contemporary example like the recent Sacred Flesh (1999), there has been little further resort to possible historical source material, like Aelred of Hexham (1110–1167) and his account of the Nun of Watton, for example. Another example might be the life of sister Benedetta Carlini, a 17th century Italian lesbian nun.
Twenty years ago, Graciela Daichan collected stories about aberrant medieval religious women, but since that time, there has been no serious historical attempt to explore what factual basis might exist for the literary depictions that often served as the basis for nunsploitation cinema.
Nunsploitation in Japan 
Catholic nun exploitation films have been a sub-genre of Japanese exploitation film since at least the early 1970s. Though christianity was never a dominant religion in Japan, Japan did encounter Christian missionaries. By taking a minority religion as their subject, it has been suggested that these "shockingly perverse and wildly blasphemous" Catholic nun films are "a way of thumbing one's nose at organized religion without attacking the more sacred beliefs of the general society". Some entries in this genre include Norifumi Suzuki's School of the Holy Beast (1974), Masaru Konuma's Cloistered Nun: Runa's Confession (1976), Kōyū Ohara's Sister Lucia's Dishonor (1978), and Wet Rope Confession: Convent Story (1979), Hiroshi Mukai's Nun: Secret (1978), Nobuaki Shirai's Nun Story: Frustration in Black (1980), and Mamoru Watanabe's Rope of Hell: A Nun's Story (1981) and Electric Bible: Sister Hunting (1992). In 1995, big-busted AV idol Mariko Morikawa starred in director Sachi Hamano's Big Tit Monastery (巨乳修道院), another Japanese variation on the nunsploitation genre.
