This film served as inspiration for the naming of the heavy metal band Black Sabbath. In 1968, the band (then called Earth) was playing a small club in Birmingham, England. Across the street was a movie theater showing the film Black Sabbath. The band noticed that more people were in line to see the movie than were to see the band. Realizing that "horror sells tickets" they decided to change the band's name to Black Sabbath.
There were additional scenes filmed with Boris Karloff introducing the segments, however AIP decided they were unnecessary and cut them from the film. Karloff would later say these introductions were some of the most fun he'd ever had on a film set.
The films title was a homage to 'Black Sunday' the previous film that Mario Bava had made for AIP. The success of that picture made the distributors select a title that was similar to that of the earlier Bava hit.
