Princess Farah refuses to marry Sinbad until Prince Kassim, her brother, is able to give his consent. However, the Prince's wicked stepmother, Queen Zenobia, has changed Kassim into a baboon in order to have her own son crowned as caliph. Sinbad, his crew, the Princess and the transformed Prince travel to a distant land, fighting every obstacle Zenobia places in their path, to seek the advice of a legendary wise man who can possibly tell how to end the spell.
This is a cracking action fantasy tale with Patrick Wayne as our hero out to restore his friend the Caliph to human form after the evil sorceress "Zenobia" (Margaret Whiting) turned him into an ape. Sam Wanamaker treats the audience as more grown up than in many of these stop-motion animation films; the monsters seem to have bit more "soul" - particularly the cyclops; and Patrick Troughton as "Melanthius" is more of a telepathic scientist than possessor of mystic powers. Ray Harryhausen is in his element and we have plenty of fun with a cast also featuring Jane Seymour and Taryn Power. It doesn't need your brain to get out of second gear, but is a very creatively put together adventure film with loads going on.
