Trivia / Black Sabbath (1963)

• Acting for Two: Boris Karloff plays both himself (as the host) in the wraparounds, and Gorca in The Wurdulak.
• Production Posse: Bava's father Eugenio created and sculpted the head for the ghost in The Drop of Water as well as the severed head for the segment The Wurdalak.
• Re-Cut: The AIP version, which reorders the segments, adds new wraparounds with Karloff, changes the score and removes the lesbian angle from The Telephone while adding a supernatural element.
• Same Language Dub: Boris Karloff is looped by Aldo Silvani in the Italian version.
• Uncredited Role: The child actor playing Ivan in The Wurdalak isn't listed in the credits, and to date their identity remains unknown. Same goes for the director of the re-shot wraparound segments in the AIP cut.
• Writing by the Seat of Your Pants: Les Baxter recorded the AIP version's entire score in a single day.
• What Could Have Been: Had Mario Bava's later film, Dr. Goldfoot and the Girl Bombs, not been a bomb in its own right, AIP were planning to hire him again to direct an adaptation of The Dunwich Horror (which they were planning to title Scarlet Friday, completing a Thematic Series with this movie and Bava's earlier Black Sunday). They had Boris Karloff and Christopher Lee in mind to star. As it stands, the film was made in 1970 without Bava, Karloff, or Lee's involvement, and it was just called The Dunwich Horror. Dean Stockwell starred.
