Fans, last weekend I viewed the 1963 classic BLACK SABBATH. This was the US release edit of the film directed by Mario Bava (released in Italy under a title that translates to something like THREE FACES OF TERROR).
The movie presents three stories, each presented by Boris Karloff, who takes an important role in the final tale, "The Wurdalak," based on a story by Count Alexei Tolstoy.
"The Wurdalak" is based on old Slavic vampire lore and includes the idea that the vampire is driven to take the blood of those he loved best in life. Ring a bell?
The second tale in the set, "The Telephone," seemed as if it might have been the springboard for the infamous "Grayson solo" episode in 1967 in which a terrorized Julia struggles to get through a night alone at Collinwood. A memorable clip from that episode is available here:
