Sergio Leone's first solo directorial effort was this colorful sword-and-sandal epic set in ancient Greece. Rory Calhoun stars as Dario, a captain in the Greek army who must travel to the island of Rhodes to destroy the huge bronze statue of Colossus, which hurls molten lead at its attackers. Dario also battles for his life in the arena and saves victims from a torture chamber before the climactic earthquake which brings the Colossus down. Many of the supporting players in this Italian-French-Spanish co-production went on to become regulars in the exploitation films of Jesus Franco. ~ Robert Firsching, All Movie Guide
