Maciste nellinferno di Gengis Khan: Mark Forest stars as Hercules in this sword-and-sandal affair from 1960 (its American release occured two years later). The film bears a striking resemblance to the like-vintage Hercules Against the Barbarians, right down to the choice of leading man. We suspect that both films were excerpted from a longer Hercules epic, then released separately to engender a higher box-office take. Oh, yes the plot: Hercules takes on the three sons of Genghis Khan, quite a remarkable feat for a superhero from ancient Greece. Jose Greci also appears in this tribute to testosterone.
