The Vampire  (1957)

Theatrical Release Information:
The Vampire

Small-town doctor Paul Beecher (John Beal) is given some strange pills by a dying elderly researcher. Later, when Paul gets a severe headache, his young daughter accidentally gives him the mystery pills. He's later puzzled by a series of strange deaths in which all the blood was drained from the bodies of the victims and then discovers the old researcher was working on a project involving vampire bats. The horrified Paul gradually begins to suspect that he himself is the killer. This adequate low-budget film combines science fiction with the classic vampire myth without advancing either very much. But the dialog is above average, and the cast is notably good for a film on this budget level, particularly lead actor Beal, and James Griffith as a very unusual visitor. ~ Bill Warren, All Movie Guide
