For the Woolner Brothers U.S. release version, under the title "Hercules and the Captive Women", the original score has been replaced by a stock score selected by Gordon Zahler. Zahler used much of the same music he had selected for the U.S. release of Kurt Maetzig's _First Spaceship on Venus (1962)_ as well as portions of the score from Jack Arnold's _Creature From the Black Lagoon (1954)_ .
