Mickey Rourke has signed on to star in Relativity Media's War of the Gods, about a Greek mythological battle, starring opposite Henry Cavill and Freida Pinto.

According to Variety, the story follows a young warrior Theseus who leads his men into battle with the immortal Greek gods to defeat evil and the powerful elder gods of the Titans in order to save mankind.

Rourke has been cast as the villain, King Hyperion. Tarsem Singh is directing.

Pinto will portray Phaedra, an oracle priestess who must join Theseus -- played by Cavill -- on his quest to prevent the cataclysmic war from erupting.
