Introduction: Deep-Sea Disaster
Let’s be honest: DeepStar Six was doomed from the start. Released in early 1989, it was the first of several “underwater sci-fi horror” knockoffs trying to cash in on the hype surrounding James Cameron’s The Abyss. Unfortunately, while The Abyss went on to showcase groundbreaking visuals, complex characters, and a genuinely thrilling aquatic setting, DeepStar Six was what you’d get if someone filmed a seafood platter attacking a military base.
Directed by Sean S. Cunningham—yes, the guy who gave us Friday the 13th—this film tries to bring slasher sensibilities into the ocean. But instead of Jason Voorhees with a scuba tank, we get… a crab. A crab that looks like it crawled out of a Red Lobster dumpster after closing time.
The Plot: When Nuclear Protocols Meet Seafood Nightmares
The story involves an experimental U.S. Naval facility at the bottom of the sea where 11 people spend their time arguing, pressing buttons, and waiting to be picked off. The Navy is apparently testing underwater colonization, but also—because it’s the 1980s—building a nuclear missile platform. Because nothing screams “sustainable living” like a reactor one malfunction away from turning the Atlantic into a hot tub.
Things go wrong when they blow open a cavern and awaken a giant crustacean. Instead of celebrating the discovery of a new species and naming it something inspiring like Cunningham’s Crab, they immediately try depth-charging it into oblivion. Of course, the monster gets mad, people start dying, and everything spirals into chaos.
The chaos, however, is less exciting cinematic thrill ride and more drunken office fire drill. Doors malfunction, people drown, systems overload, and Miguel Ferrer accidentally convinces a computer that World War III has started, leading to a nuclear explosion that makes Chernobyl look like a campfire mishap.
The Monster: Fear the Lobster Special
The big reveal is that the creature is a giant eurypterid (or “Depladon”), basically an ancient sea bug with claws. It’s supposed to be terrifying. Instead, it looks like a giant animatronic crab you’d see in a seafood restaurant’s nightmare promotional video. Imagine being stalked by something that looks like it should come with melted butter and a lemon wedge.
The creature design is clunky, rubbery, and rarely shown clearly—probably because the director realized it looked like a Halloween decoration bought on clearance at Kmart. When it finally chomps people, the result is less “horrific” and more “comedy sketch.”
The Characters: Disposable Seafood Snacks
The crew is an assortment of cardboard archetypes shoved into a steel can. Their job isn’t to be compelling; it’s to scream, flail, and eventually die.
-
McBride (Greg Evigan): The designated hero, mostly notable for his hair, which remains fluffy despite being underwater. He’s supposed to be cool under pressure, but spends most of his time reacting like someone who just found out they’re out of mayo.
-
Joyce Collins (Nancy Everhard): McBride’s girlfriend, who exists mostly to be rescued and scream convincingly.
-
Dr. Scarpelli (Nia Peeples): Marine biologist who actually wants to study things, which in this movie is the same as tattooing “first to die” on your forehead.
-
Snyder (Miguel Ferrer): The only character with any life. He’s a cowardly, twitchy mechanic whose stress-induced meltdown causes him to nuke the seabed. His death by rapid decompression—exploding like a fleshy piñata—is the only memorable part of the movie.
-
Dr. Van Gelder (Marius Weyers): The arrogant commander whose main talent is barking orders and walking backward into harpoons.
-
Captain Laidlaw (Taurean Blacque): A noble leader who goes out like a champ early on, which is this film’s polite way of saying “we ran out of budget for this actor.”
By the end, you’re rooting for the crab. At least it’s trying.
Special Effects: Mostly Special in the Kindergarten Sense
The effects are a mix of low-budget miniatures, questionable matte shots, and the occasional bucket of fake blood. When the creature attacks, the editing becomes frantic—as if the filmmakers are trying to hide the fact that the monster prop can barely move its claws.
The underwater base itself looks like a bad theme park ride. The control rooms are all blinking lights and giant buttons labeled things like “NUCLEAR LAUNCH,” because subtlety is for losers. Whenever water floods in, it’s painfully obvious someone just turned on a hose behind the camera.
And don’t get me started on Snyder’s decompression death. While iconic for its sheer absurdity, it looks less like a man exploding and more like someone popped a giant water balloon filled with tomato soup.
Pacing: The Real Horror
The worst part of DeepStar Six isn’t the monster. It’s the fact that you have to wait an hour before it even shows up. Until then, it’s just endless exposition, melodramatic arguments, and close-ups of sweaty actors pretending to push important buttons. The film tries to build suspense, but what it really builds is boredom.
By the time the creature finally starts munching people, you’re almost relieved—at least something is happening. Unfortunately, the deaths are so repetitive and awkwardly staged that even this turns dull.
Dark Humor Highlights
-
Nuclear missiles detonated by accident because the mechanic panicked? That’s less sci-fi horror and more typical Monday at the Pentagon.
-
The crab is attracted to light, meaning this billion-dollar naval installation could’ve been saved by just turning off a lamp.
-
The big final battle involves McBride killing the monster with a flare gun. Yes, the U.S. Navy’s best defense against ancient sea monsters is the same thing you’d use to signal a passing yacht.
-
Characters spend half the movie yelling “We have to decompress!” which, coincidentally, is also what audiences were muttering to themselves in the theater.
Legacy: Deep-Sixed
DeepStar Six is remembered today, if at all, as one of the many underwater horror films of 1989. Unfortunately, it was quickly overshadowed by Leviathan (which at least had Peter Weller), The Abyss (which had James Cameron), and even the so-bad-it’s-good Lords of the Deep. By comparison, DeepStar Six is the wet cardboard of the bunch.
It tried to combine military sci-fi with aquatic monster horror, but ended up with the cinematic equivalent of soggy fish sticks. Even Miguel Ferrer’s gloriously unhinged meltdown can’t save it.
Conclusion: Sink This Ship
In the end, DeepStar Six is a film that confuses claustrophobic terror with endless bickering, and creature thrills with a giant crab puppet lunging at the camera. Its pacing is glacial, its characters are flat, and its monster looks like it belongs in a children’s aquarium exhibit.
If you want undersea horror done right, watch The Abyss or even Leviathan. If you want to waste 100 minutes watching a crab ruin everyone’s day, then by all means, DeepStar Six awaits.
