The score was by Carlo Martelli, but contained uncredited excerpts from Rimsky-Korsakov's Scheherazade, Ippolitov-Ivanov's Procession of the Sardar, and Franz Reizenstein's music written for Hammer's original "mummy" film.
Because union rules in Britain decreed that one person could not be credited as the writer, producer and director of a film, writer/producer/director Michael Careras adopted the name "Henry Younger" for his screenplay-a deliberate analogy to the name "John Elder", which was Hammer producer Anthony Hinds' writing pseudonym.
