If you’re in the market for a film where immortality is achieved via flashlight and guinea pig sabotage, then congratulations: The Asphyx is your new morbid bedtime story. This 1972 British horror-science fiction film, directed by Peter Newbrook in his only feature as director, is a delightfully peculiar oddity—equal parts philosophical parable, gothic fever dream, and Victorian TED Talk on why playing God leads to decapitations.
The movie dares to ask the big questions. What is death? What is the soul? And how long can one man monologue before someone gets guillotined?
Starring Robert Stephens and Robert Powell, The Asphyx doesn’t waste its time with your typical blood-splattered vampire antics or undead wandering in foggy graveyards. No, this one offers something deeper: the terrifying possibility that life may, in fact, never end. Especially if you’re dumb enough to trap your personal Grim Reaper in a glowing fish tank and lose the key.
Plot: Death Becomes… Avoidable?
Set in a fog-drenched version of Victorian England that looks like it was sponsored by cobwebs and sorrow, the film introduces Sir Hugo Cunningham (Stephens), a gentleman scientist who dabbles in photographing the moment of death—which is either parapsychological research or the worst hobby since Victorian dentistry.
In these morbid snapshots, Hugo notices a smudge hovering near the newly departed. His parapsychology club assumes it’s the soul. Hugo, not one to go with the obvious answer, hypothesizes instead that it’s an asphyx—a death sprite from Greek mythology that apparently shows up right before you kick the bucket. It’s kind of like the Angel of Death, but way more photogenic.
Things spiral from academic curiosity to full-blown H.P. Lovecraft meets Frankenstein when Hugo discovers he can trap the asphyx using a phosphorus-based spotlight and a garden hose. Naturally. With help from his disturbingly eager son-in-law Giles (Robert Powell), Hugo begins experimenting—first on guinea pigs, then on himself and his family. Because in Victorian England, what says love like non-consensual eternal life?
Family Experiments and Guillotine Mishaps: What Could Go Wrong?
Things go downhill—well, decapitated really—when Hugo tries to give his daughter Christina and Giles a taste of immortality. Giles’ job? Operate a guillotine over his fiancée’s neck and almost kill her, so the asphyx shows up. This is what passed for romance before dating apps.
Unfortunately, the guinea pig (clearly a metaphor for Fate, or at least a rodent union rep) chews through the hose, stopping the water from dripping on the phosphorus and rendering the death-ray-asphyx-trap inert. The guillotine drops, Christina is beheaded, and Giles is suddenly reconsidering the whole “forever” thing.
Giles demands immortality anyway, but sabotages the process because eternal life without your decapitated fiancée just isn’t all it’s cracked up to be. This ends in literal explosive results—gas, oxygen, matches, a boom—and Hugo is left immortal, alone, and devastated. That’s what you get when you trust a guinea pig with your eternal soul.
Robert Stephens: A Madman with Style
Let’s talk about Robert Stephens, who gives Sir Hugo a performance so committed you’d think he was being paid in actual immortality. With his wild eyes and Victorian mutton chops, Stephens turns Hugo into the kind of man who owns too many books, not enough common sense, and absolutely no ethical boundaries.
He radiates both paternal warmth and subtle derangement, which makes his descent from philanthropist to death-hoarder feel tragic rather than cartoonish. By the end of the film, when he’s crawling through modern-day London traffic like a geriatric Nosferatu, you actually feel for him—even if he’s now the kind of man who gets hit by two cars at once and doesn’t flinch.
Science! But Make It Terrifying
One of The Asphyx’s greatest strengths is how seriously it takes its nonsense. This is a film where immortality is achieved with hoses, glowing rocks, and enthusiastic guesswork, yet it’s shot like a BBC historical drama and acted with Shakespearean weight. There are no winks to the camera. No ironic detachment. Just cold, grim British determination to wrestle with death using Home Depot supplies.
The science is… dubious. The morality? More so. At one point, Giles volunteers to murder his girlfriend for the sake of science and immortality, and Hugo basically responds with, “Splendid, I’ll get the guillotine.” It’s like if Mary Shelley rewrote The Island of Dr. Moreau after a particularly nasty divorce.
That Ending: When Eternal Life Means Never Escaping the Sequel You Deserve
In its final gut-punch of irony, we see a disfigured, immortal Hugo stumbling through 1970s London with his undying guinea pig in tow. He’s crushed beneath a multi-car pileup—and survives. One police officer is horrified. The other has the right reaction: stunned silence, probably wondering if it’s too late to change professions.
It’s a final image as bleak as it is hilarious. Hugo has finally beaten death, and in doing so, has become an undying, crusty Victorian roadkill relic. He’s the punchline to his own god complex—and that, friends, is what we call poetic justice with a side of existential dread.
Final Thoughts: A Bizarre Little Masterpiece That Refuses to Die
The Asphyx isn’t perfect. The pacing is slow. The effects are charmingly clunky. The guinea pig gets more screen time than several human characters. And yet… it works. It’s earnest, unsettling, and darkly funny in all the right places.
This isn’t a horror movie in the jump-scare sense. It’s a tragedy wearing a lab coat, a meditation on mortality dressed up like a mad science lecture, and a warning to all would-be gods: be careful what you cage—it might be the only thing keeping you human.
★★★½ out of 4.
Recommended for fans of vintage horror, existential dread, and rodents with plot-altering chewing habits.
