The Psychotronic Film Society’s own Wednesday night series of underappreciated or downright obscure features from around the globe continues Aug. 29 at The Sentient Bean on Forsyth Park with a special 122nd birthday tribute to the famed English writer Mary Shelley, author of the inestimably influential 1818 novel “Frankenstein.” In honor of the legacy of her creation, they’ll show one of the sleaziest and least-known entries in the long line of motion pictures based on Shelley’s reanimated monster: “Frankenstein ’80,” a low-budget Italian-made shocker from 1972 that is generally regarded as one of the most unintentionally funny horror films ever made.

The film, which bears only a slight resemblance to the plot of Shelley’s book, concerns a doctor who obsessively experiments at stitching body parts from a number of corpses together into a human-ish creature he calls “Mosaic.” As one might imagine, “Mosaic” is brought to a sort of life, and promptly escapes the doctor’s supervision and sets about attacking a wide variety of buxom Italian and German women, much to the chagrin and bewilderment of onlookers. Although the special makeup effects in this guilty pleasure of a grindhouse flick were handled by a young Carlo Rambaldi (who’d later earn three Oscars for his stunning effects work on the 1976 remake of “King Kong” as well as 1979′s “Alien” and 1982′s “E.T. The Extra-Terrestrial”), the rest of the film is a gonzo mess of nonsensical character development that is ineptly dubbed into spoken English. Come prepared to chuckle and gasp at the depraved stupidity of it all. 8 p.m. showtime, with discounts on craft beer and organic wine during the show.
