The mightiest adventurer of them all! In this sumptuous sword-and-sandal feast, Rory Calhoun (Apache Territory, The Colossus of Rhodes) stars as Marco Polo, the legendary 13th-century explorer who journeys to China with the aim of expanding world trade. There he meets Princess Amuroy, amorously played by Yôko Tani (The Savage Innocents, Samson and the 7 Miracles of the World), and an old hermit who has just invented gunpowder. With this explosive new “magic,” Marco builds a special cannon and spearheads a rebellion against an evil warlord. Directed by Piero Pierotti (Hercules and the Masked Rider) with additional scenes by Hugo Fregonese (The Death Ray of Dr. Mabuse), it’s an epic, action-packed peplum adventure in sweeping CinemaScope and eye-popping Technicolor.
