<Li> Jason was not betrayed by Acastus in the classical tale . Jason openly told King Aeëtes that he had come for the Fleece . The king promised Jason could have it if he performed three tasks, knowing full well they were impossible . However, Jason was able to complete the tasks with the help of Medea . It was not the Hydra that protected the Fleece but rather a dragon . Jason did not slay it, but instead Medea cast a spell on it, causing it to fall asleep . Jason sowed the dragon's teeth into the ground, not Aeëtes . Jason defeated the "dragon's offspring" (the spartoi) by making them fight amongst themselves and destroy each other, rather battling them with his colleagues . </Li> <Li> One of the two Argonauts killed by the skeletons is Castor, who in Greek mythology would perish much later as the result of a feud with Idas and Lynceus . The other is Phalerus, who in mythology would also survive the adventures of the Argonauts . </Li> <Li> The film ultimately omits the story of Medea killing and dismembering her own brother, Absyrtus, to help Jason and the Argonauts escape . as are the episodes with Cyzicus, the Gegeines and the Argonauts' stay on the isle of Lemnos . </Li> <Table> <Tr> <Td> </Td> <Td> This section needs expansion .
