Cemetery of the Living Dead (1966)

AKA "Terror Creatures from the Grave" or "Tombs of Horror". In a tale supposedly inspired by Poe--good luck figuring out what story!--it seems the late Dr. Jeronimous Hauff, dabbler in matters occult, left a legacy. A curse, actually. Now ancient victims of the plague are rising from their graves to avenge his murder, for he was most assuredly done in by his lady wife, with help from a few folk who failed to consider the consequences. (Well, of COURSE, there are consequences! This IS a horror movie. And a Euro-horror at that, complete with Barbara Steele.)
