The vampire-anti-heroine, played by Ingrid Pitt, has distinct lesbian tendencies. She prefers sinking her fangs into the bosoms of comely young women, though when required she’s not averse to giving the works to an interfering local doctor and a manservant.
Not much of a story, but the screenplay [from an adaptation by Harry Fine, Tudor Gates and Michael Style of J. Sheridan Le Fanu’s story Carmilla] has all the needed ingredients. Dank interiors, eerie exteriors and stagecoaches, plenty of blood, a couple of unconvincing decapitations, stakes in the vampire’s heart, the sign of the Cross, etc. Fairly flat dialog doesn’t provide much of the unconscious humor that usually gives a lift to this type of entertainment.
