Horror of the Blood Monsters on AllMovie

Perhaps the most flagrantly re-packaged and re-titled no-budget project from notorious schlockmeister Al Adamson, this goofy melange culls footage from no less than three separate films -- including a Filipino caveman/monster movie (shot in black-and-white, then tinted fruity colors by Adamson) and the sci-fi flicks Unknown Island and One Million B.C.. If a plot can be detected amid this car crash of disassembled storylines, it might involve the efforts of a scientist (John Carradine) to send an expedition to a distant planet of space-vampires to halt their invasion of Earth. Once there, the astronauts don't find any vampires, but they do come across legions of oversized iguanas and rowdy Filipino cavemen. Aside from the distinction of having distinguished cinematographer Vilmos Zsigmond behind the camera, this film holds some kind of record for the most re-titlings in movie history.
