Jason and the Argonauts (1963)

Hero Jason needs to avenge the murder of his family by the usurper Pelias, but first he must find the legendary Golden Fleece. Even with the help of the goddess Hera and a crew of the strongest, fastest, bravest men aboard the Argo, the journey is not straightforward and requires many feats of strength and endurance. I have no idea how accurate this is to classic mythology, but that matters less than the special effects here. There’s some incredible work to be seen from the giant bronze Talos to the flying Harpies to the incredible skeleton army. That last bit is so iconic that I recognized it immediately from the replica seen during my days playing Rollercoaster Tycoon.
