Demons of the Mind is a 1972 British horror film, directed by Peter Sykes and starring Gillian Hills, Robert Hardy, Patrick Magee, Michael Hordern and Shane Briant.[2] It was produced by Anglo-EMI, Frank Godwin Productions and Hammer Film Productions, and written by Christopher Wicking, based on a story by Frank Godwin.


A wealthy widower locks up his two grown-up children, afraid that they will go mad, as did his wife. He then invites a doctor of dubious reputation to supervise their mental health and cure them of the unnatural attraction they have for each other. Meanwhile, in the vicinity of the mansion, murders are happening in the local village and a travelling priest arrives to help drive out any local demons.



The film's working title was Blood Will Have Blood.[3] "Hammer thought there were too many bloods," said Wicking later. "I don't think anybody knew it was a quote from Shakespeare because they would have said no to that."[4]

Principal photography took place from 16 August to September 1971.[3]

Peter Sykes was hired after Hammer were impressed by his work on Venom. The movie was based on the life of Franz Mesmer.[1]

Wicking says "there was a sort of snobbery about" the film "which I think is a bad thing."[4] He says Sykes wanted Paul Scofield and then Dirk Bogarde and when neither of them wanted to do it, Hammer felt they could not ask their usual leading men, Peter Cushing and Christopher Lee, and the role was given to Robert Hardy, which Wicking thought was a mistake.[4]

Sykes said the film was well reviewed and has become a cult film but was a commercial disappointment. "It wasn't a recognisable subject; there was no Frankenstein in it," said Sykes.[1]

Critical reception

The Monthly Film Bulletin wrote: "Demons of the Mind opens with a coach rattling through the forest and closes with torch-wielding villagers descending on the wicked Baron. But although it is made with style (Peter Sykes proves adept at recreating the oppressive atmosphere of Hammer's earlier films), the content is meagre, and unfortunately the days are past when a string of horror-film clichés (terrified coachmen, beautiful screamers, crimson rose) could stand in lieu of a plot. It may be a measure of the makers' intentions that the part played by Gillian Hills was originally meant for Marianne Faithfull (former pop idol Paul Jones still plays the male lead); but with the script providing few pointers, the three juveniles manage only shallow performances, while Michael Hordern and Patrick Magee plump for gross overplaying. The film's principal distinction is its violence, mostly gratuitous and, in the case of the climactic bloodbath, thoroughly unpleasant."[5]

Time Out called the film "an exotic, Wildean horror story, visually as extravagant and tantalising as a decadent painting" that is "badly let down, though, by some grotesque overacting".[6]

The Hammer Story: The Authorised History of Hammer Films wrote of the film: "oblique, ambitious and suffused with an air of primal dread, Demons of the Mind deserved better."[3]
