The original music score by Coriolano Gori is featured only in the Italian version of the film which differs significantly from the German cut (i. e. it features more action scenes and less plot / character development while running shorter). The score of the German version consists solely of archive music from other films, including The Death Ray of Dr. Mabuse (1964), Death and Diamonds (1968), Hard Women (1970) and Jungfrauen-Report (1972).
