Clash of the Titans DVD. 2010. 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 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.
