black sabbath (1963)

aka I Tre volti della paura. The Three Faces of Fear. The Three Faces of Terror. Les Trois visages de la peur.
A horror in three parts, introduced by and featuring Boris Karloff as the Wurdalak. Firstly, The Telephone where a woman recieves a series of phone calls from her ex-pimp who has escaped from prison. She enlists the help of her lesbian ex-lover Mary, who comes over, but this just serves to rack up the tension and claustrophobia as they await the coming of Frank. Second we have The Wurdalak: A 19th Century tale of a young man who stumbles on a family awaiting the return of their father, who they now believe to be a Wurdalak. A walking cadaver who feeds on the blood of the living, preferably close friends and family. The final story is The Drop Of Water. In Victorian London a woman is called to a house to dress the corpse of a medium, and whilst doing so steals a ring. She is subsequently plagued by a fly and visions of the corpse. The fantastic photography and lighting lends extra atmosphere to these three very claustrophobic and stylish stories. See this film, but preferably in the original Italian version. AIP for some reason decided to tamper and released it with the stories rearranged and eliminating some of the sub plot elements.
