I watched, the 1960 black and white Universal International release, The Leech Woman on Svengoolie. An old woman answers an ad by endocrinologist, Dr. Paul Talbot, about aging. She says that she was brought to America 140 years ago as a slave and that if he can fund her trip back to Africa she’ll show him the secret to eternal youth. He agrees and takes his wife, who he wants to make beautiful again, so that he’ll love her again. Things go pretty bad from here. Dr. Talbot is played by Phillip Terry (Mannequin, The Monster and the Girl, Wake Island, Bataan) and his wife June is Coleen Gray (Destination 60,000, The Phantom Planet, Nightmare Alley, Red River, The Killing). Other stars are Grant Williams (The Incredible Shrinking Man, The Monolith Monsters, PT 109, Brain of Blood, Doomsday Machine, also known as Escape from Planet Earth),
and produced by Joseph Gershenson (Curse of the Undead, Monster on the Campus, Step Down to Terror, House of Dracula). They used a lot of stock footage, in the film, with a good portion coming from the movie Tanganyika (1954).
