Immortals is the story of the ancient Greeks, and the mortal battle for an immortal weapon: the Epirus Bow. King Hyperion (Mickey Rourke) scours the country in search of it so he can release the Titans, a group of vanquished gods that lost a heavenly war. Henry Cavill plays Theseus, a mortal peasant who was unknowingly taught by Zeus and may be the only thing stopping the king from completing his task.
