Yahoo! Movies has got its hand on three official posters for "Clash of the Titans". Though two of the images have been leaked before, the other one-sheet is still fresh and features Sam Worthington's Perseus in an epic war as well as presents several other characters of the movie. "Clash of the Titans" is a modern version of the 1981 Greek mythology film. It revolves around Perseus. Helpless to save his family from Hades, he volunteers to lead a mission to defeat the vengeful god of the underworld before Hades can seize power from Zeus and unleash hell on earth. (Aceshowbiz.com)
