In "Clash of the Titans," the ultimate struggle for power pits men against kings and kings against gods. But the war between the gods themselves could destroy the world. Born of a god but raised as a man, Perseus (Sam Worthington) is helpless to save his family from Hades (Ralph Fiennes), vengeful god of the underworld. With nothing left to lose, Perseus volunteers to lead a dangerous mission to defeat Hades before he can seize power from Zeus (Liam Neeson) and unleash hell on earth.
