The Incubus is a title that keeps following horror readers around. It appears on a 1981 Canadian supernatural slasher, on a 2010 independent film set in a small community called Spoon River, and on Adrian Cave’s dark anthology The Incubus 2. Because the same name has been used for separate projects, newcomers can quickly become confused about what belongs to which story. The truth is simpler than it looks: there is no shared universe, only a shared creature and a shared sense of dread.
The creature at the centre of all these works is one of the most intimate monsters in horror. It does not announce itself loudly or push its way through locked gates. Instead, it comes to people while they are resting, often in the form of a desire they cannot control. Film descriptions are direct about this. The 1981 picture is described in reviews as a supernatural horror film about an incubus raping and killing women, while the newer fiction attached to the name trades in demonic desire, nightmares and supernatural horror. That personal menace explains why the idea has survived for so many decades in so many different formats.
The Incubus (1981): The Canadian Cult Film
Most viewers meet the creature through the 1981 film, which is catalogued in many references simply as Incubus. It is a Canadian supernatural slasher directed by John Hough and starring John Cassavetes, Kerrie Keane and John Ireland. The plot follows a small-town doctor who tries to discover who, or what, is responsible for a series of violent sexual murders. One popular review calls the picture a tight mystery with genuinely horrific murders, and that balance between detective work and gruesome set pieces is a large part of the reason it became a cult favourite.
The supernatural threat in the film is deliberately personal. An incubus is a demon associated with night and intimate violation, and this screen version takes that folklore seriously by presenting a presence that rapes and kills women while remaining invisible to the town around it. The back-of-video blurb used on early home releases put the idea in theatrical terms, reminding audiences that the film is based on the novel by Ray Russell and declaring that the ultimate power of evil returns to a small town and only one man can discover the form it has taken.
Artwork and home releases have kept the title circulating for more than four decades. Some retrospective reviews date the film to 1982, while film encyclopaedias usually settle on 1981, and this small confusion adds to the sense that the title itself is restless. In spring 2025 the story found its way back into shops when HMV listed a disc edition for 7 April 2025 at £14.99, wrapped in a description of a quiet New England town that becomes the site of a grisly murder and assault leaving a young man dead.
The Incubus (2010): A Small Town Facing Disappearance
The name returned in 2010 in a completely different form. This The Incubus, directed by Marcie Gorman and Shayne Leighton, is set in Spoon River, a town of roughly 500 people. The synopsis centres on Marnie Rose, a 19-year-old enduring abuse in the same small community, and the story opens at a moment when nothing in her life feels safe or stable. The horror of the film is tied as much to that personal suffering as to the supernatural events that begin to close in around the town.
Change arrives when new neighbours move in and a group of mysterious teenagers settles nearby. Almost at once, people in the neighbourhood start to come down with an unexplained disease. A mysterious student enrols, residents fall ill, and the town slowly begins to face disappearance. The letterboxd-style summary used to advertise the film puts it in four words: behind his eyes, a mystery unravels. It is a quieter, moodier picture than the 1981 version, and it shows how flexible the incubus idea can be when it is removed from the mechanics of a slasher plot.
The Incubus Films at a Glance

There is no continuity between the two films. They were directed by different teams, set in different places and built around different kinds of suspense. Yet both share the same underlying fear: a community discovers that something has crossed from folklore into ordinary life, and the people who should be safest are the ones most at risk. That single idea gives the name The Incubus its staying power.
Adrian Cave and the Modern Use of the Incubus
Independent horror fiction has continued to find fresh angles on the same nightmare. Adrian Cave is an author who specialises in paranormal, supernatural and horror books, and his catalogue is rooted in the kind of stories that treat the unseen as genuinely dangerous. His online home, Paranormal Books at paranormal-books.net, describes the promise behind every release simply: every book opens a doorway into the unknown. Readers who come to the site expecting ghosts, demons, cryptids, haunted places and occult mysteries will find a growing library built around those dark borders of reality.
The incubus belongs naturally in that world. It is a demon that exploits human weakness, often appearing at night or in moments of loneliness, and its legend connects directly to the themes that run through much of Cave’s work: desire, obsession, sleep and the moment when a nightmare refuses to stay inside the dream. His contribution to the title is the collection THE INCUBUS 2: 20 Dark Tales of Demonic Desire, Nightmares and Supernatural Horror.
Why the Twenty-Story Format Suits Demonic Horror
A significant part of Adrian Cave’s catalogue consists of themed anthologies containing twenty complete, standalone stories. This structure does something clever for readers. Because every story introduces different characters, locations and supernatural dangers, no single tale needs to carry the weight of a long novel. Readers can enjoy one story at a time without memorising a continuous plotline or mastering a complicated shared mythology. The collection keeps its energy through variety while remaining anchored to a central theme.
That approach helps with a subject like the incubus, which works best when it appears in different disguises. One story may present the demon as a seductive figure, another as a predator hiding in a marriage, and another as something ancient that has waited inside a locked room for decades. The anthology format allows each version to end with its own punch, and the title of the collection, THE INCUBUS, acts as a warning rather than a promise of safety.
Stylistically, the dark tales draw on motifs that reappear throughout Cave’s longer fiction. The result is a body of work filled with:
- Restless spirits and unfinished business
- Demons that exploit grief or desire
- Haunted houses, castles, hospitals and hotels
- Forbidden doors, sealed rooms and hidden corridors
- Nightmares crossing into reality
- Ordinary people confronting impossible forces
- The fear of being watched, followed or called by something that should not know them
Readers who arrive with an interest in the incubus legend will recognise these patterns immediately. The demon in the folklore does not appear in a ruined graveyard or a cursed forest. It appears in places people trust, often when they are alone or half asleep, and it uses desire as the trap. Adrian Cave’s anthologies make full use of that intimacy, which is why the stories stay with readers long after the final page.
Frequently Asked Questions
What kind of creature is an incubus in horror fiction?
In supernatural horror, an incubus is a demonic force associated with night visits and forbidden desire. The clearest description in the films is simple: a demon that rapes and kills women. What makes the creature frightening is its ability to hide, often appearing as an ordinary person or working through the desires of its victims, which is why it creates so much suspense before it is revealed.
