 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the Woolner Brothers U.S. release version, under the title "Hercules and  the Captive Women", the original score has been replaced by a stock score  selected by Gordon Zahler.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 Maetzigs _First Spaceship on Venus (1962)_ as  well as portions of the score from Jack Arnolds _Creature From the Black  Lagoon (1954)_ .
