The Manson Massacre[5] is a 1972 sexploitation horror film directed by Kentucky Jones and starring MaKee K. Blaisdell and Debbie Osborne.

[6][7] The film follows the charismatic leader of a religious cult, Invar, who coerces a group of women into committing murders via coercion, beatings, and sexual games.

[3] The film received some criticism upon its 1976 release, and was banned from being shown Maryland along with Snuff due to its depiction of sex and violence.

[9] Mike McPadden of Crime Feed wrote of the film: "By way of sloppily arranged depictions of a nonprofessional cast engaging in fake-looking orgies and faker-looking gore murders, The Manson Massacre conjures the notion of a "movie" only in the fact that it's shot on film and, remarkably, once played to paying audiences in theaters.

Makee K. Blaisdell plays Manson stand-in Invar, a monk-robed occult guru who sleeps in a coffin and cohabitates with five young women.
