Originally known as Horror of the Blood Monsters, this melange of a movie was put together by schlock auteur Al Adamson out of … not one … not two … but three different films, including a black and white Filipino monster movie. With additional scenes (shot by Vilmos Zsigmond of Close Encounters and The Deer Hunter), Adamson made a mess of a movie about space vampires and the scientists who travel to their planet to stop them. When Blood Monsters flopped, Adamson rereleased it four times under different titles, including this one. […] The artwork of stars John Carradine, Robert Dix and Vicki Volante was done by well-known comic artist Gray Morrow.
The actors’ names are set in Eurostile, “A fantastic adventure to a distant, hostile world!” in Univers Bold Italic.
