Adventures ensue, featuring a winged horse, three appropriately hideous witches, and the Gorgon Medusa. Perseus, having discovered he is the son of Zeus, takes on the job of defeating Hades. Hades appears to the court and tells them that Andromeda must be sacrificed to the Kraken. Cepheus's queen, Cassiopeia (Polly Walker, who has previous form in this kind of thing – she was Attia in HBO's Rome) boasts that their daughter Andromeda is more beautiful than the gods. In heaven, Zeus is persuaded by Voldemort, sorry, I mean Hades (Ralph Fiennes) that the mortals can be brought back in line by unleashing the Kraken, the creature which the Olympian gods created to defeat their old enemies, the Titans.
