The Slumber Party Massacre Collection

The Massacre films are three interconnected series of slasher films executive-produced by Roger Corman: the Slumber Party Massacre series (1982–2021), the Sorority House Massacre series (1986–1990) and the Cheerleader Massacre series (2003–2011), distributed by New World Pictures and New Concorde. The series also features the standalone film Sharkansas Women's Prison Massacre (2015), and the reboot film Slumber Party Massacre (2021). All three of the original Slumber Party Massacre films, and the first Sorority House Massacre film, were given limited theatrical releases, while Sorority House Massacre II and III, and both Cheerleader Massacre films were released direct-to-video, and the 2021 reboot released to the Syfy network. The franchise is notable for being primarily directed by women, who direct every Slumber Party Massacre film and the first Sorority House Massacre film.
