Finally found a copy of 1963 movie Jason and the Argonauts on DVD and been looking for this DVD for over 10 years.

This is probably the best stop-motion animation film ever made depicting Greek myth. Jason recruits the Argonauts to crew his ship, and along the way they encounter a variety of mythic creatures, including the 100-foot bronze god Talos, the batlike Harpies, the seven-headed reptilian Hydra, and an army of skeletons wielding sword and shield.

The last sequence with skeletons remains one of Hollywood's iconic fight scene that have never been topped. highly recommended
