The Vampire(Movie, 1957)

The Vampire is a 1957 American horror film produced by Arthur Gardner and Jules V. Levy, directed by Paul Landres, and starring John Beal and Colleen Gray. Its plot follows a San Francisco physician who inadvertently ingests pills laced with the blood of vampire bats, leading him to take on vampiric qualities. Like 1956's The Werewolf, it offered a science fiction take on a traditionally supernatural creature, although the films were produced by different production companies. The film was released theatrically in San Francisco as the bottom half of a double feature with The Monster That Challenged the World. When released to television, the film was given the alternative title Mark of the Vampire, though it is unrelated to the 1935 film of the same name starring Bela Lugosi. ()
