Sinbad and the Eye of the Tiger (1977)

Synopsis
Famed stop-motion animator Ray Harryhausen concocts a collection of fantastic creatures -- including a saber-tooth tiger, a chess-playing baboon, a giant walrus and three banshees -- for this follow-up to The Golden Voyage of Sinbad. Patrick Wayne stars as Sinbad, who seeks the hand of Princess Farah (Jane Seymour) in marriage but cannot get her brother, Prince Kassim (Damian Thomas), to agree to the match because he has been turned into a baboon by his evil stepmother. In order to receive the blessing of Farah's brother, Sinbad must travel to a far away realm and find a wizard named Melanthius (Patrick Troughton), the only one who can break the evil spell placed upon Kassim. ~ Paul Brenner, All Movie Guide
