Blood on Satan’s Claw (1971)
Blood on Satan’s Claw, aka “Satan’s Skin”, is a 1971 British horror film made by Tigon British Film Productions and directed by Piers Haggard. The film was written by Robert Wynne-Simmons, with additions by Piers Haggard, and stars Patrick Wymark, Linda Hayden and Barry Andrews. It is set in 17th century England, and tells the story of a village taken over by demonic possession.
In his 2010 BBC documentary series A History of Horror, writer and actor Mark Gatiss referred to the film as a prime example of a short-lived sub-genre he called “folk horror”, grouping it with 1968′s Witchfinder General and 1973′s The Wicker Man.
