My Bloody Valentine (1981): The Canadian Mining-Town Slasher

Every slasher of 1981 was shot on a location. Only one was shot down a mine.

That distinction sounds like trivia and it is the whole film. George Mihalka took his crew to Sydney Mines in Nova Scotia and put them underground in a working colliery — real shafts, real cages, real methane protocols, a crew in real gear because the alternative was dying. You cannot fake that space and nobody has tried since. Watch the underground third of My Bloody Valentine and then watch any horror film that built a mine on a stage, and the difference is not production value. It is atmosphere that came free with the location and could not have been bought.

The legend

The town of Valentine Bluffs has not held its Valentine’s dance in twenty years. The reason is Harry Warden: a miner trapped by a methane explosion, caused because the supervisors on shift left early to get to the dance and skipped the gas check. Warden survived by eating the men who did not. He came out, he killed the supervisors, he cut out their hearts, and he told the town that if the dance was ever held again he would come back.

Twenty years later the town decides it has grieved enough. The dance is announced. A heart arrives in a heart-shaped box.

It is, as legends go, an unusually good one — better than Cropsy, better than Jason’s mother, better than the drowning-at-camp boilerplate the cycle was churning out — and the reason is that it is a story about industrial negligence. The horror originates in a manager cutting a corner to make a party. That is a folk legend a mining town would actually tell itself, and the film treats it exactly as such: passed on by an old barman, disputed by young people who think it is nonsense, and believed absolutely by everyone over fifty.

The only slasher about work

Here is the argument for the film, and I think it holds up against anything in the cycle.

The American slasher is a film about leisure. Camp, prom, the babysitting shift, the holiday cabin, the sorority — the genre’s entire geography is the geography of not working, which is why its victims are almost always teenagers and why its moral machinery is about pleasure being punished. That machinery gets a full accounting in the slasher’s body count as moral accounting, and it is the reason so many of these films feel identical: they are all set in the same three weeks of adolescence.

My Bloody Valentine is set in a town where everybody has a job and the job is the same job. The young cast are miners. They go down the pit, they come up, they drink, they have a rivalry over a woman, they go back down. The film’s romantic triangle is between two men who work the same seam. The Valentine’s dance is a works do. The town’s authority figures are a police chief and a mine manager, and the manager’s instinct, when bodies start appearing, is to keep production going and keep it quiet — the exact reflex that caused the original disaster.

Nothing else in the subgenre is doing this. The film’s fear is not of a stranger from outside; it is that the place you work will kill you, that it has killed people before, and that management already knows and has decided the numbers are acceptable. That is a horror film about being employed, and it arrived in 1981 wearing a pickaxe.

The craft

The killer’s costume is the design coup: full miner’s kit, oilskins, boots, helmet lamp, and a gas mask with round glass eyes and a corrugated snout. It is genuinely frightening for a reason that has nothing to do with menace. It is correct. Everyone else underground is wearing the same thing. In the pit, the killer is invisible because he is dressed for the job, and the film uses that constantly — figures at the far end of a passage, lamps moving, and no way to know which light is a friend.

The lamp is the other piece of technique. Underground, the only light is on people’s heads, which means the camera can only see what someone is looking at, and Mihalka exploits this ruthlessly. A head turns and a whole area of the frame goes black. The film’s best sequences are simply people looking in the wrong direction. Carpenter got the same effect in a suburb by using the depth of a street — the shape standing in the part of the frame you had stopped watching, the technique anatomised in Halloween — and Mihalka gets it for free because a mine is a place where the dark is a physical fact.

Paul Zaza’s score deserves its own paragraph, because it makes a decision almost no slasher of the period made. Zaza — a Canadian composer whose fingerprints are all over the tax-shelter horror of those years — writes underground music that behaves like weather rather than threat. It drones. It sits under scenes at a level you stop hearing, and it does not spike when a lamp swings past something. The most famous cue is a ballad about Harry Warden himself, played straight, a folk song written for a legend that the film has just spent ninety minutes treating as a legend. Ending a slasher on a mournful ballad about the killer is the sort of choice a film makes when it thinks the town is the subject and the murders are the symptom.

The pacing is patient in a way 1981 rarely allowed. The film spends real time on the town, the pub, the shift, the relationships, and it earns its last half hour by making you believe the place exists before it starts emptying it.

Cut to pieces

Then the ratings board arrived. My Bloody Valentine opened in the aftermath of Friday the 13th and the moral panic that followed it — the campaign against slasher violence that had critics reading out plot summaries on television as a public warning — and the studio removed something in the region of nine minutes of effects work to avoid an X.

What was removed was the entire payoff. The film’s set-pieces were built as gags with a beat, and the cuts land on the beat, so for thirty years the version people saw simply stopped mid-idea. A restored edition eventually reinstated most of the footage, sourced from surviving material of lesser quality, so the gore now arrives visibly degraded — a scratchy, softer image cut into a clean one. That seam is oddly moving. You can see precisely which frames the industry decided the public should not have.

Watch the restored version. The film makes sense in it.

The real ancestor

Halloween is the obvious parent for the holiday hook, and Black Christmas is the true origin of the date-on-the-calendar slasher — Bob Clark got there in 1974 and the whole apparatus of Prom Night, April Fool’s Day and this film descends from him, a line drawn in the twelve films that invented the slasher.

But the real grandparent of My Bloody Valentine is folk horror. A closed community, an old crime, a ritual the elders say must not be performed, a younger generation who perform it anyway, and the land itself keeping the account. Move the mine to a field and change the pickaxe to a wicker frame and you have the same film. That is why it survives when its 1981 cohort does not: it is built on a structure older than the slasher, and the slasher furniture is the surface.

Quentin Tarantino has called it his favourite of the cycle. He is not wrong, and the reason is probably this: it is the only one that believes in the town.

The case against

The young cast are variable, and the love triangle that carries the first act is the least interesting thing in the film. The whodunit is thin — the film plays fair but the pool of suspects is small and the misdirection is not sophisticated. Mihalka is a better director of place than of people, and the pub scenes go on.

And there is an honest structural objection: the film’s best material is underground and it takes an hour to get there. Everything above the surface is a competent 1981 slasher. Everything below it is unlike anything else in the genre. A film that has to be waited out for its best hour is asking a lot.

The gas-mask design also does the film one disservice worth admitting. A killer with no face and no body language is a killer with no presence, and My Bloody Valentine has nothing like the personality of the shape in Halloween or the sheer physical wrongness of Cropsy. The costume is frightening as an object and inert as a character; it works in the wide shots and it works in the dark, and any time the film has to give the killer something to do in a lit room it deflates. The mask is a location effect that happens to be worn by a person.

Where to find it: the special edition with the restored footage, in whatever form it currently takes. The theatrical cut is a mutilated object.

Spoilers below

Harry Warden is dead, and has been. The man in the gas mask is Axel — one of the young miners, part of the triangle, whose father was one of the supervisors Warden killed. Axel was a child, and he saw it.

That reveal is where the folk-horror structure closes. The legend was true, the legend is finished, and the killing continues anyway — because the story got into a child and grew. The mine does not need Harry Warden any more. It has a second generation now, and it will have a third. The film’s last movement puts Axel underground where his father died, in the gear his father wore, doing what the man who killed his father did, and it does not treat this as a twist. It treats it as an inheritance.

The ending is the film’s hardest choice. Axel is not stopped in any final sense — he loses an arm to the machinery and goes deeper into the shaft rather than out of it, promising his return, and the last thing the film gives you is a voice receding into a tunnel that goes on for miles under a town full of sleeping people. There is no body. There is no closure. The mine takes him back.

That is a strange and rather beautiful landing for a Valentine’s slasher, and it is entirely consistent with the seventy minutes before it. The film has been telling you from the first scene that this place buries things and that the things do not stay buried, and the ending simply declines to pretend otherwise. The dance was always going to be held again. Someone always leaves the check undone.
