Instant Orgy (1967)

"Instant Orgy" (1967), the quirky little sexploitation flick from Barry Mahon.
This short film, running somewhere between 5 and 10 minutes, is a textbook example of late '60s low-budget erotica with a dash of unintentional comedy. The setup is gloriously simple: a group of women are at a meeting—supposedly about charity funds—when someone slips a potion labeled "Instant Orgy" into their drinks. What unfolds isn’t the chaotic free-for-all the title suggests, but a tame, almost wholesome scene of the women peeling off their outer layers and dancing in their underwear to a bouncy surf rock beat. It’s less lustful frenzy and more like a pajama party gone mildly risqué.
The cast features the Bennett twins, Dawn and Darlene, who popped up often in Mahon’s quick-and-dirty productions, alongside a handful of others like Sharon Carter and Barbara Doll. Acting is beside the point here—everyone’s just along for the ride, delivering lines with the earnestness of a school play. The film’s single-room setting and barebones production scream shoestring budget, but that’s part of its charm. The surf rock soundtrack is a highlight, injecting a playful, beachy vibe that’s more goofy than seductive.
