Errol Flynn's immediate followup to his 1953 swashbuckler Master of Ballantrae was Il Maestro di Don Giovanni--or, as it was known in America, Crossed Swords. Flynn plays a Don Juan-like adventurer named Renzo, who fights and romances his way through all sorts of Italian court intrigue. His principal foe is the wicked coucillor (Roldano Lupi) of the Duke of Sivona (Piero Tordi), who intends to oust the Duke and claim Sivona for himself. In between the usual sword duels, Renzo dallies with the Duke's buxom daughter (Gina Lollobrigida). Crossed Swords failed to make a dent in the US, a fact that Errol Flynn would attribute to United Artists' lack of interest in promoting the property.
