Boris Karloff enjoyed working with Bava on "Black Sabbath", and he praised his work to both Christopher Lee and Vincent Price who would later go on to work with Bava in "The Whip and the Body" and "Dr. Goldfoot and the Girl Bombs" respectively. Plans were made to reunite Bava with Karloff and Lee to work an adaptation of "The Dunwich Horror", provisionally titled "Scarlet Friday". The project was later taken away from Bava after the critical and commercial failure of "Dr. Goldfoot and the Girl Bombs", and was released as "The Dunwich Horror" directed by Daniel Haller; the film was made without Karloff and Lee's involvement.
