The Psychotronic Film Society’s long-running weekly showcase of underappreciated or marginalized feature films from around the world continues with a rare public screening of one of the more gripping survival movies ever made, director Cy Edenfield’s intense 1965 action drama “Sands of the Kalahari.”

It was filmed on location in Southwest Africa, in what is now known as Namibia, and Spain, this tale of a plane crash in a desolate, desert region of Africa that leaves a small group of adult strangers fighting for their lives against starvation, dehydration, jealousy, greed and a large troop of incredibly strong and angry baboons. It stars Stuart Whitman, the American actor who almost became James Bond, Stanley Baker, one of the most beloved British dramatic actors of all-time, Susannah York, the beautiful blonde actress who came in many ways to epitomize the “Swinging London” scene of the late 1960s, and Theodore Bikel, among others. It’s something of an overlooked gem packed with solid acting and believably dangerous situations in seemingly harsh physical conditions.

Shown to commemorate the 43rd anniversary of Stanley Baker’s untimely demise at the age of 48 from lung cancer, the PFS will screen the full, uncut, widescreen theatrical cut. Showtime 8 p.m.
