On Oct. 2, the Psychotronic Film Society continues its long-running and award-winning weekly night series of overlooked or downright obscure feature films from around the world in the cozy, DIY environment of the Sentient Bean Coffeehouse on the Southern end of Forsyth Park. In honor of Halloween, the PFS will screen a different little-known, unusual horror film every Wednesday in October, starting this week with the obscure but extremely cool 1972 British thriller-fantasy “The Asphyx.”

Though not a product of the U.K.’s famed Hammer Film Studios (which became almost synonymous with gothic, moody British horror of the ’60s and ’70s), this forgotten period feature boasts excellent set design and terrific acting from all concerned. It’s the strange tale of a mid-Victorian-era scientist who becomes obsessed with the idea that he has discovered a way to identify and even trap the “Asphyx,” an evil, tormented spirit described in Greek mythology that supposedly rushes into a person’s body and shoves out their soul just moments before the person dies.

Believing this discovery holds the secret to immortality, he engages in a series of bizarre experiments in order to prove his hypothesis. A legitimately strange film, for decades it was only available in poor-quality, severely edited copies. However, the PFS will screen a fully uncut and beautifully restored version of the original, full-length theatrical version rarely seen since the early 1970s. This is a rare chance to see it as the filmmakers intended, on the big screen. 8 p.m. showtime, with a full vegetarian dinner menu available and discounts on craft beer and organic wine during the movie.
