Satan's Slave (1976 film)

Satan's Slave is a 1976 British supernatural horror film directed by Norman J. Warren. It was written by David McGillivray and stars Candace Glendenning, Michael Gough, Martin Potter, and Barbara Kellerman. Its plot follows a young woman who, after surviving a car accident, stays on the country estate of her uncle and cousin, unaware they are both necromancers who intend to sacrifice her to resurrect the spirit of a supernaturally gifted ancestor.

The film, a production of Warren's newly formed company Monumental Pictures, was funded by producers Les Young and Richard Crafter with their own money and shot almost entirely on location in Pirbright and Shepherd's Bush in December 1975. The following year, re-shoots were conducted to film additional material as well as more violent alternative versions of existing scenes, with the aim of increasing the film's appeal to Far East audiences.

Satan's Slave was originally released as a B movie in the United Kingdom, with screenings beginning in December 1976. The film was released in the United States three years later under the title Evil Heritage. Critical reaction to the film has been mixed, with aspects such as the acting, script and plot drawing a variety of responses.
