Watching Horror of the Blood Monsters is like slipping into a coma during a bad acid trip, waking up in a garage full of lava lamps and taxidermy mistakes. This isn’t a film. It’s a prank that got out of hand, an existential dare from director Al Adamson to see just how far he could push an audience before someone walked into traffic. It’s a migraine in movie form—loud, incoherent, and bleeding profusely from the ears.
Here’s the “plot,” and I use that term like a drunk uses a cocktail napkin for legal defense. In the far-flung future (read: 1980s as imagined by someone who never escaped 1957), Earth is suffering from a vampire plague. Yes, vampires. Because why not. So what’s the obvious solution? Send a spaceship full of square-jawed men to a distant planet where the problem probably started, even though that makes no sense and involves science that was likely cobbled together with crayons and desperation.
The crew includes a handful of interchangeable space cadets, a couple of mood rings pretending to be computers, and poor John Carradine, who looks like he wandered onto the set while trying to find the craft services table and was blackmailed into reading cue cards. Carradine delivers his lines with the enthusiasm of a man deeply aware he’s in a cinematic war crime. He wears a shiny future-cape and acts like he’s narrating a bedtime story to Satan himself. You can practically hear his soul evaporate between takes.
Once our crew lands on the planet (spoiler: it’s the Philippines in a loincloth), the film devolves into a hellish mashup of stolen black-and-white jungle footage, repurposed caveman flicks, and Adamson’s original “new” material that’s been color-tinted like a gas station Slurpee gone bad. There are lava cavemen. There are bat people. There are lizard men with papier-mâché heads and no clear purpose. It’s like someone spun a giant wheel labeled “public domain nonsense” and glued it all together with popsicle sticks and lies.
You see, this movie is partially cobbled together from an older Filipino movie called Tagani, which Adamson bought for pennies and “reimagined” the same way a toddler reimagines your tax forms with a crayon. The whole thing is colorized—barely. The planet’s atmosphere is described as being made of “chromatic radiation,” which is director-speak for “we’re tinting the film green for five minutes because we spilled Mountain Dew on the reel.” Sometimes it’s red, sometimes blue, sometimes it flickers like the projector is having a seizure.
And speaking of seizures, the editing. Oh dear God. Transitions happen at random. One minute we’re watching a fight scene where a caveman throws a Styrofoam rock; the next we’re back in the spaceship where a man is tapping a blinking panel that looks suspiciously like an old washing machine. There’s no sense of rhythm or time. It’s like someone took two reels of film, threw them in a blender, poured the results onto a roll of duct tape, and called it cinema.
The special effects are the real monsters here. The “bats” are rubber Halloween decorations on strings, flailing in the wind like they’re trying to escape the script. The spaceship’s interior looks like it was designed by a failing high school theater kid who got high on Elmer’s glue. And the blood? Oh yes, it’s in the title after all. The blood looks like ketchup that’s been left out in the sun—thick, gooey, and nowhere near anything resembling human biology. People are constantly getting stabbed, clawed, bitten, or mauled by invisible forces, and it all looks like a horror-themed slap fight at a tomato festival.
Characters die with the conviction of soap opera extras. One guy gets attacked by the bat people and screams like someone just stepped on his flip-flop. Another is sucked into a lava pit and reacts like he forgot to pay his electric bill. There’s a scene where someone “falls off a cliff,” which is really just them stepping gently behind a shrub. The soundtrack wails and screeches through these scenes like a broken saxophone being shoved through a blender. It’s not music. It’s an auditory lawsuit.
And the dialogue? Sweet hell. It’s not just bad—it’s cosmically stupid. People shout science fiction jargon like “ionic thrusters,” “blood virus infection rate,” and “gamma sector overload” like those words actually mean something. At one point, a character warns, “We must be cautious—the blood vampires have adaptive chroma capabilities.” That’s a sentence written by a man who lost a bar bet.
The pacing is molasses in a coma. Scenes linger long after they should’ve been mercy-killed. Characters walk from point A to point B while the camera records every agonizing step. There’s a 12-minute sequence of cavemen grunting and waving sticks around like they’re trying to swat invisible bees. Meanwhile, the crew of the spaceship delivers expository dialogue with the urgency of a sloth reading Shakespeare. This is a movie that dares you to remain conscious.
So what does Horror of the Blood Monsters do right? Well, it ends eventually. That’s something. And there’s a certain car-wreck charm to the whole mess. If you’re into ironic pain and cinematic masochism, this is the Mount Everest of garbage. It’s not just bad—it’s Al Adamson bad, which is its own category of sin. The man didn’t make movies so much as he cobbled together disasters with duct tape, borrowed footage, and a prayer to the God of tax write-offs.
Final Verdict:
If Ed Wood and Tommy Wiseau had a love child raised on expired meat and pulp novels, and that child tried to make a sci-fi horror movie in their dad’s shed, you’d get Horror of the Blood Monsters. It’s a movie that defies logic, taste, and even space-time. It doesn’t deserve your attention—but if you do watch it, you’ll never forget it. Much like food poisoning.
One star, awarded posthumously to John Carradine’s dignity. May it rest in peace.
