Horror of the Blood Monsters - Region 1 DVD

One of cult movie director Al Adamson's most popular films, known for its use of weird color effects by "Spectrum-X," stars horror icon John Carradine as scientist Dr. Rynning, who leads a space journey to a distant planet of blood-sucking vampires intent on contaminating Earth. While exploring the planet, the crew becomes entrapped by warring tribes of primitive vampire-like men and, in order to escape bloody death, must battle snake-men, bat-demons, and the other hideous denizens of this evil world!
