Nightmare Castle

Aroview: Atmospheric gothic horror, with below-par Italian stylings and a dual role for cult actress Barbara Steele.

Playing a pair of sisters, Steele becomes consecutive wives of a mad scientist after the first is tortured to death in an electrical experiment to regenerate human blood. Soon hallucinatory madness begins to waft through the air, leading to a bloody nightmare of a conclusion. Note: this is the (shorter) 67m American cut of the film.
