According to the Greeks, the Minotaur was a legendary half-man, half-bull who lived on Crete and demanded the sacrifice of humans, according to the scripters of this typical Italian costume drama, the real story is about twin sisters (both played by Rosanna Schiaffino), one evil and one pure-hearted. This story has the Minotaur as a secondary figure, all bull, who stands up on his hind legs to indicate his god-like status. The real hero is Theseus (Bob Mathias) who ultimately kills the Minotaur (for the Greeks, too) because he has fallen in love with the good sister and has to save her from being sacrificed.
