Synopsis by Mark Deming
An invader from space has sinister designs on the world's blood supply in this sci-fi thriller. Paul Johnson (Michael York) is a mysterious stranger who arrives in Los Angeles and moves into a luxurious estate in Beverly Hills, hiring a private nurse, Amanda (Elizabeth Barondes), to help him with his rare medical condition, as well as a driver and errand boy, Jeremy (Richard Belzer). However, Amanda soon thinks there's something strange about Paul, and after consulting with a physician, Dr. Rochelle (Mason Adams), they discover that Johnson is actually an alien who is stockpiling reserves of blood for the dying residents of his home planet. Not of This Earth is the second remake of 1957's low-budget cult classic; Roger Corman, who directed the original film, served as executive producer for this version.
