of the '70s have emerged such as Cody Jarrett's Sugar Boxx (2009) and Steve Balderson's Stuck! (2010). Both of these films mimic classic WiP films by including typical WiP film characters, predictable scenes, and similar plots overall. Italian films Italian exploitation directors have produced scores of WiP films with far more graphic sex and violence than those produced in the U.S. Bruno Mattei directed Women's Prison Massacre (1985), Caged Women (1984), and Jail — A Women's Hell (2006). Other films include Women in Fury (1985) and Caged Women in Purgatory (1991). The Nazi exploitation subgenre centers on the same theme of captive women suffering abuses in war-time prison camps. Many of these films were developed in the late 1970s and the early 1980s as the industry continued to grow. Films such as SS Experiment Love Camp, SS Camp 5: Women's Hell, Hell Behind Bars and Hell Penitentiary directed by Sergio Garrone in 1983, Gestapo's Last Orgy (1977) directed by Cesare Canevari, Helga, She Wolf of Spilberg (1978) and Fraulein Devil (1977) directed by Patrice Rhomm, SS Hell Camp (1977) directed by Luigi Batzella, Women in Cell Block 7 (1973) directed by Rino Di Silvestro and Nazi Love Camp 27 (1977) directed by Mario Caiano were partly inspired by the U.S./Canadian Ilsa series.

Prime examples include Bamboo House of Dolls (1973) with Birte Tove, and Great Escape from a Women's Prison. Comfort Women (1992) is based on real events. Chinese prostitutes are abducted by Japanese soldiers and used for brutal scientific experiments at the notorious Unit 731 medical camp. A Chinese Torture Chamber Story (1994) and its sequel are based on historical records of China's Qing dynasty. The topic of sex "is usually considered taboo in traditional Chinese society", which makes the film industry scandalous and frowned upon by many. One of the very early examples of the genre in Japan began with Death row Woman, a noir drama made by the master of J-horror Nobuo Nakagawa in 1960, although the plot doesn't focus entirely inside of the prison. After, the women prison films are often made into a series based on popular characters from manga comics such as Prisoner Maria and the Joshu Sasori series, most known by the Meiko Kaji films.
