The Werewolf is a low-budget American 1956 science fiction horror film, produced by Sam Katzman and directed by Fred F. Sears from a script by Robert E. Kent. Like The Vampire (1957), it offers a science fiction view of a traditionally supernatural creature, although the films were by different production companies. The film's music was credited to Mischa Bakaleinikoff.
Duncan Marsh (Steven Ritch), a mild-mannered man, finds himself lost in a remote village called Mountaincrest. His mind is clouded, but he learns later that Emory Forrest (S. John Launer) and Morgan Chambers (George Lynn), two scientists, injected him with a special serum containing irradiated wolf's blood when he was suffering from amnesia after being in a car accident. The wolf's blood, for unknown reasons, changed the previously gentlemanly Duncan into a vicious, bloodthirsty werewolf.
