Ebay seller mis-identifies movie and identifies Helga Liné as Hélène Chanel! The photos are from MISSIONE SABBIE ROVENTI (1966) with Howard Ross (aka Renato Rossini).
Another one I came across on eBay:
Portuguese DVD for FURY OF HERCULES which stars Brad Harris but they used a photo of Gordon Scott’s head. That’s NOT his body. So, Gordon Scott is now a substitute for Steve Reeves and Brad Harris.
