Incubus is a considerably more tasteful film than its above synopsis might suggest. The demonic rapes all take place off-screen, for instance. John Hough is on sometimes imaginative form like the scene where a librarian is attacked and notably one scene with a woman being dragged under a bathroom cubicle door by an unseen assailant. Overall though, the pace is too sedate indeed, Incubus comes out resembling something more like a made-for-tv horror film. Despite a good 1976 source novel from Ray Russell, the assembling of ideas is pedestrian and never too clear. With John Cassavetes at the centre, playing with doleful hangdog expression, the human drama never gets a chance at leaving the station. The ending however comes with a subtle and effective surprise.
John Houghs other films are:- Hammers Twins of Evil (1972), the haunted house film The Legend of Hell House (1973), the Disney films Escape to Witch Mountain (1975) and Return from Witch Mountain (1978) about psi-powered alien kids, the Disney ghost story The Watcher in the Woods (1980), the British boys air hero Biggles (1986), American Gothic (1987), Howling IV: The Original Nightmare (1988) and Bad Karma/Hells Gate (2002).
Incubus is based on a 1976 novel by horror writer Ray Russell. Elsewhere, Ray Russell wrote a number of screenplays including Mr. Sardonicus (1961) about a man with a frozen grin and Zotz! (1962) about an academic who comes into possession of a coin with powers for William Castle, Premature Burial (1962) and X The Man with X-Ray Eyes (1963) for Roger Corman, as well as The Horror of It All (1964) in the UK and the theatrically released Grand Guignol tv pilot Chamber of Horrors (1966).
