Let’s get this out of the way—Incubus is not the kind of movie you recommend to your aunt, unless your aunt has a morbid curiosity about demonic sexual assault, small-town witch lore, and John Cassavetes looking like he’d rather be anywhere else but still giving a performance too good for this kind of sleaze. It’s grim, it’s nasty, and it’s about as subtle as a jackhammer in a funeral home. And yet… it works. Against all odds, this Canadian supernatural slasher manages to be atmospheric, disturbing, and just the right amount of weird to stick in your brain like a bad dream.
The Premise: Welcome to Galen, Where Everyone Knows Your Name (and Possibly Your Blood Type)
The movie takes place in the tiny Wisconsin town of Galen, which sounds quaint until you realize it’s basically Twin Peaks without the pie or coffee—just a growing body count and something evil lurking in the shadows. Women are being brutally attacked in ways that make seasoned lawmen blanch, and the attacks are linked not just by grotesque violence, but by an inexplicable amount of—well—let’s call it evidence and move on.
Dr. Sam Cordell (John Cassavetes) is the town’s reluctant hero, a widowed doctor trying to keep a handle on the carnage while raising his teenage daughter. He’s joined in the investigation by Sheriff Hank Walden (John Ireland, wearing the weary lawman look like a second skin) and Laura Kincaid (Kerrie Keane), a nosy reporter who knows more than she’s letting on. Throw in Tim Galen, a local teen with psychic nightmares about the attacks, and you’ve got yourself a cozy little murder club—with a supernatural twist.
The Atmosphere: Fog, Fear, and a Dash of Canada
Director John Hough knows how to shoot small-town horror. There’s a crisp autumn chill to the visuals, a sense of isolation that makes the violence hit harder. Filmed in Guelph, Ontario, the movie manages to make you believe in this Wisconsin setting—a place where the most exciting thing should be the high school football game, but instead is wondering which neighbor is secretly a shape-shifting sex demon.
Albert J. Dunk’s cinematography bathes the film in shadowy interiors and overcast exteriors, like the weather itself is trying to warn everyone to stay indoors. The hospital scenes have a clinical coldness that makes the violence feel even more clinical—frighteningly matter-of-fact, not cartoonish.
Cassavetes: The Reluctant Horror Star
John Cassavetes didn’t make a lot of horror films, but when he did (Rosemary’s Baby, The Fury, and now this), he brought an intensity that elevated the material. As Dr. Sam Cordell, he’s not just phoning it in between art films—he’s genuinely magnetic. He plays Sam as a man trying to balance medical logic with the creeping suspicion that something supernatural is at work. He’s also the only one who can deliver medical dialogue about, uh, unusual forensic findings with a straight face.
Kerrie Keane holds her own as Laura, managing to be equal parts helpful investigator and femme fatale. Watching her go from plucky reporter to something far darker in the final moments is one of the movie’s best slow-burn reveals. And John Ireland’s Sheriff Walden is exactly the kind of grounded presence you need when the plot is this bonkers.
The Horror: When a Slasher Meets a Demonology Handbook
Unlike most slashers of its era, Incubus doesn’t just give you a guy in a mask—it gives you something ancient, otherworldly, and far nastier. The attacks aren’t shot for titillation; they’re meant to unsettle, and they succeed. The kills have a grim specificity that suggests someone actually thought about how a supernatural entity would work in a small-town setting.
And then there’s Tim’s nightmares—feverish, surreal flashes of torture and shadow that bleed into reality. These sequences have a dreamlike quality that’s miles away from the cheap jump scares of other early ’80s slashers.
The Ending: A Reveal That’s Both Obvious and Perfect
By the time we learn who the incubus has been using as its human mask, you might guess the twist—but the way it’s delivered still lands. The final scene is one of those “oh no” moments where your stomach drops and you realize the film has been setting you up the whole time. It’s grim, it’s abrupt, and it leaves you with that rarest of horror film feelings: the suspicion that the evil isn’t over just because the credits roll.
The Dark Humor: Unintentional, but Delicious
It’s not a comedy by any stretch, but there’s an undeniable pulp absurdity here. You’ve got Cassavetes deadpanning about “unusually large quantities” of certain bodily fluids while looking like he’d rather be back directing A Woman Under the Influence. You’ve got a small-town library casually stocking occult texts like it’s just part of the Dewey Decimal System. And you’ve got the sheriff looking perpetually two minutes away from asking if this couldn’t all just be solved with a strong cup of coffee and a good night’s sleep.
Even the incubus itself—never fully shown, but felt—has a kind of cosmic pettiness to it. It’s like a supernatural creep who can manifest anywhere in town but keeps choosing bathrooms, libraries, and rural farmhouses. You’re a centuries-old shapeshifter, and that’s how you spend your time?
Why It Works (When It Really Shouldn’t)
On paper, Incubus sounds like an exploitation flick you’d find on a discount VHS rack in 1987. In execution, it’s unsettling, moody, and oddly memorable. It mixes slasher tropes with supernatural horror and detective-story pacing, anchored by actors who treat the script like it’s Shakespeare in a haunted barn.
It’s not a film for the faint of heart—its subject matter is disturbing, and it doesn’t shy away from showing the aftermath of its violence. But it’s also got a strange integrity to it, a commitment to the dread it’s building.
Final Verdict
Incubus is grimy, gutsy, and ghoulishly good in that way only early ’80s Canadian horror can be. It’s the kind of movie that feels like you found it on late-night TV in 1985, watched half-asleep, and then wondered for years if you’d dreamed it—until you finally saw it again and realized, nope, it’s just that weird.
