Producer Charles H. Schneer began his movie career at Columbia Studios and there collaborated and encouraged stop motion animator and wizard of special effects Ray Harryhausen in his envelope-pushing endeavours. Of their many collaborations which extended to Schneer's own production companies, the producer considered Jason and the Argonauts their finest.
A golden fleece awaits at the end of the world. A gift of the Gods to the far country of Colchis, the fleece has guaranteed its prosperity and peace. Jason hopes it will do the same as an inspiration to the people of Thessaly. The usurper Pelias has ruled Thessaly for twenty years after killing King Aristo, Jason's father. Now come of age, Jason desires to take back the throne and free the minds and hearts of his people.
The cast of Jason and the Argonauts is an interesting mix of British actors steeped in tradition and Shakespeare, the glamorous Nancy Kovak as Medea, Honor Blackman a year before Goldfinger, a beginner for the lead in Todd Armstrong, and Italian speaking extras. The
Jason and the Argonauts was the final of four Schneer and Harryhausen films scored by Bernard Herrman following The 7th Voyage of Sinbad, 1958, The Three Worlds of Gulliver, 1960, and Mysterious Island, 1961.
