Clash of the Titans is a 2010 fantasy film and remake of the 1981 film of the same name. As with the 1981 film, the story is very loosely based upon the Greek myth of Perseus. Directed by Louis Leterrier and starring Sam Worthington, the film was originally set for standard release on March 26, 2010. However, it was later announced that the film would be converted to 3-D and was finally released on April 2, 2010. The film begins with a narration that explains the three Olympians who battled the Titans long ago: Zeus, Poseidon, and Hades. Hades provided their means of defeating the Titans with his creation, the Kraken. After the Titans' defeat, Zeus created humans and ruled them while Poseidon ruled the sea, but Hades, having been deceived by his brother Zeus and forced to rule the Underworld, learns an alternative way of gaining power from humans different from his brothers receiving theirs from human prayer: through fear.
