Okay, fellow tapeheads, let’s rewind to 1990. You’re scanning the horror aisle, the fluorescent lights buzzing overhead, the scent of plastic clamshells and slightly stale popcorn in the air. You’ve already devoured the first two Slumber Party Massacre flicks, maybe even grinned at the knowing wink of Part II’s rockabilly killer. Then your eyes land on it: Slumber Party Massacre III. The cover promises more mayhem, more co-eds in peril, and, of course, that signature power tool. You grab it, maybe along with a forgotten actioner and a pizza, ready for some late-night cathode ray tube thrills. But does this third trip to the slaughter deliver the goods, or is it just running on franchise fumes?

Right off the bat, Slumber Party Massacre III feels... different. We ditch the suburban setting and relocate to a swanky beach house where a group of friends are throwing – you guessed it – a slumber party after a day of intense volleyball. The setup is pure early 90s slasher boilerplate: attractive young people making questionable decisions while a mysterious killer lurks nearby. This time, the threat feels less supernatural and more grounded, centering around a creepy neighbor (played with suitable sleaze by Brittain Frye) and the lingering trauma of one of the girls, Jackie (Keely Christian), whose sister was a victim of a previous massacre.
Directed by Sally Mattison, who mostly worked in television afterward, the film doesn't quite capture the subtle feminist undertones Amy Holden Jones wove into the 1982 original, nor does it embrace the outright absurdity of Deborah Brock's Slumber Party Massacre II (1987). Instead, it plays things relatively straight, aiming for suspense and shocks within the familiar slasher framework. The script, penned by Catherine Cyran (who also wrote and directed Dangerous Waters aka White Water Summer the same year), hits the expected beats: jump scares, red herrings, and characters splitting up when they absolutely shouldn’t.

Where SPM III earns its keep, especially for us fans who appreciate the old ways, is in its commitment to practical effects. Forget the sterile, weightless digital blood splatters of today. When the driller killer strikes here, the impact feels messy and visceral, just like you’d expect from a spinning power tool meeting flesh. Remember how those kills looked back then, maybe slightly obscured by tracking lines on your worn-out tape? They felt brutally real in their own way. There’s a raw, tactile quality to the gore – latex appliances, spurting blood packs, the whole messy nine yards – that modern CGI often lacks. The effects team clearly put their efforts into making the drill sequences memorable, and for the most part, they succeed in delivering the gruesome goods expected from the title.
One fascinating slice of "Retro Fun Fact" goodness: to keep costs down, a hallmark of producer Roger Corman's New Concorde Pictures, Slumber Party Massacre III was actually filmed back-to-back with Sorority House Massacre II. They utilized many of the same locations, primarily a large house in the Hollywood Hills (standing in for our beach locale here), just redressing the sets and using much of the same crew to maximize efficiency. That kind of B-movie ingenuity is part of the charm of this era – making the most out of limited resources to get the scares on screen! It reportedly cost under $500,000 to make, a shoestring even back then, aiming squarely for the reliable home video market where these sequels thrived.


The cast does what’s required for a late-cycle slasher flick. Keely Christian makes for a capable enough final girl as Jackie, burdened by trauma but resourceful when the drill starts whirring. The other partygoers fill their archetypal roles effectively, delivering dialogue that ranges from functional to occasionally amusingly dated. Keep an eye out for M.K. Harris as Maria; genre fans might recognize her from popping up later in Leprechaun 2 (1994). While no one’s likely to win awards here, the ensemble conveys the necessary panic and eventual terror convincingly enough to sell the situation.
The killer's identity reveal is perhaps less surprising than the filmmakers intended, leaning into familiar tropes rather than genuinely shocking twists. But let's be honest, were we renting Slumber Party Massacre III for intricate plotting or for creative kills and a suspenseful chase? For many of us, the main draw was seeing that power drill put to grim use, and the film doesn't skimp on that promise. The final confrontation delivers the expected stalk-and-slash thrills, making good use of the beach house setting.
So, does Slumber Party Massacre III hold up? Well, it depends on what you’re looking for. It lacks the subversive edge of the original and the gonzo energy of the second installment. It’s very much a product of its time – a direct-to-video slasher sequel made efficiently and aimed squarely at horror fans hungry for more kills. The pacing can drag a little between the set pieces, and the characters aren't deeply developed.
However, viewed through the warm, fuzzy lens of VHS nostalgia, there's an undeniable charm. It delivers decent practical gore, a committed killer, and that specific early 90s vibe. It’s a comfortable, predictable slasher that doesn’t rewrite the rulebook but provides 87 minutes of serviceable stalk-and-slash entertainment. It might not be the crown jewel of the franchise, but it understands the assignment. I distinctly remember seeing this on the rental shelf, the slightly worn cover promising exactly the kind of uncomplicated, drill-centric horror perfect for a Friday night.

Justification: While competent for its low-budget aims and featuring solid practical gore effects that fans appreciate, SPM III suffers from a predictable plot, less memorable characters compared to its predecessors, and a generally derivative feel. It delivers on the slasher basics but doesn't innovate or achieve the cult status of the first two films. It's a perfectly average, late-era franchise entry.
Final Thought: It might not boast the smarts of the first or the sheer weirdness of the second, but Slumber Party Massacre III offers a final, functional blast of practical-effects drill carnage before the franchise faded – a quintessential slice of early 90s direct-to-video horror.
