The Scorpion King 2: Rise of a Warrior - Russell Mulcahy

In Ancient Akkad, Mathayus grows up as the proud son of Ashur, a captain in the world-renowned military corps of Black Scorpions, first-rate bodyguards, most of which are sent to courts wide away. By objecting to young Mathayus joining the corps, Ashur incurs the undying enmity of ruthless generalissimo Sargon, gets killed and the orphaned knave is shipped off to a desolate training camp for six years by king Hammurabi's clemency. When he returns as a Black Scorpio, Sargon has bloodily seized the throne and demands cruel proof of blind loyalty. Mathayus refuses, becoming a chased hero. With youth friends, the resourceful Greek Pollux and various mercenary warriors, he embarks on a daring quest to obtain a legendary sword from Sargon's magical ally, the war-goddess Astarte.
