First, in Clash of the Titans, Perseus' assistant and companion is Io. Io has been Perseus's companion since birth, and after her death during the pursuit of Medusa, she is brought back to Perseus by Zeus. However, in ancient stories, Io is actually Perseus' very distant grandmother and has no role in the Perseus myth. Second, the depiction of Perseus' birth is different in the two versions. Clash of the Titans depicts Zeus as a human who slept with Danaë. Nevertheless, Pindar asserts that Perseus "we say, was born of the golden rain", the form in which Zeus took to impregnate Danaë. Third, much variation lies in the events surrounding Danaë and those leading up to the search for the Gorgons' heads. In Clash of the Titans, Danaë is killed by her husband Calibos and placed in a trunk with Perseus until she is found by a fisherman, Spyros. After a conflict with Hades which led to the death of Perseus' family, Perseus arrived in Argos where, in order to save the kingdom and Andromeda from the Kraken sent by the gods, Perseus set off in search of the Graeae who led him to Medusa. In ancient texts, Danaë was still alive when she was discovered by the fisherman Dictys in Seriphos, and her brother the king of Seriphos, Polydectes, fell in love with her. Polydectes was eager to push Perseus aside so that Danae would accept his love, so he sent Perseus to retrieve the Gorgons.
