The Leech Woman (1960)

An endocrinologist (Phillip Terry) and his older wife (Coleen Gray) travel to Africa where he hopes to discover a rare plant that will reverse the aging process. It is there that that the wife discovers how little she means to her husband and how he has been using her. But she gets her revenge. This minor piece of sci-fi horror is rather absurd but it's done well enough and anchored by a strong performance by that underrated actress Coleen Gray that makes up for the rather preposterous narrative. The African scenes are clearly shot on a sound stage with stock footage of jungle landscapes and animals inserted to dupe the gullible that it was actually shot there. Directed by Edward Dein. With Grant Williams (THE INCREDIBLE SHRINKING MAN), Gloria Talbott, John Van Dreelen, Estelle Hemsley and Kim Hamilton.
