I always find with these stop-motion animation films that the wonderful Harryhausen creations always far out-act the human talent! Sadly, here is no different - Todd Armstrong in the title role and Nancy Novak as " Medea" are as wooden as the Argo in this retelling of the ancient Greek myth. It is still, however, an exciting action adventure though, with plenty of episodes to keep it moving along as Jason fights monsters and treachery to seek out the legendary Golden Fleece from the distant land of Colchis. It's got a decent enough, largely British, supporting cast with Honor Blackman standing out as his patron "Hera" and Nigel Green making for a wonderfully over-the-top "Hercules", but the spoils definitely go to Talos, the Harpies and the skeleton battle is fabulous.
