A small town doctor mistakenly ingests an experimental drug made from the blood of vampire bats which transforms the kindly medic into a bloodthirsty monster.
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 Coleen 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.
