Fantastic Planet

Fantastic Planet French La Plante sauvage , Czech Divok planeta , lit. The Wild Planet is a 1973 cutout stop motion science fiction allegorical film directed by Ren Laloux, production designed by Roland Topor, written by both of them and animated at Ji Trnka Studio. The film was an international production between France and Czechoslovakia and was distributed in the United States by Roger Corman. The story, which shows humans living on a strange planet dominated by giant humanoid aliens who consider them animals, is based on the 1957 novel Oms en srie by French writer Stefan Wul.

In the distant future, the gargantuan blue humanoid Draags have brought human beings who are called Oms as a play on the French word for man, Homme from Earth to the planet Ygam, where they maintain a technologically and spiritually advanced society. They consider them animals, and while some Oms are kept as pets by Draags, others live in the strange wilderness and are periodically slaughtered by the Draags who wish to keep their population controlled. Draags have much longer lifespans than Oms, but reproduce much less.When an Om mother is teased to death by three Draag children, her orphaned infant is found by Master Sinh, a key Draag leader, and his daughter Tiva, who keeps the boy as a pet and names him Terr. She loves Terr and is careful not to hurt him, but, instructed by her parents, keeps him under control, for example by giving him a collar that can pull him in any direction at Tivas wish. She brings Terr to sessions in which she receives her education using headphones that transmit knowledge into her mind, and a defect in his collar allows him to receive the knowledge too. Around the time that Tiva grows into her teens and first performs Draag meditation, which allows the species to travel with their minds, she loses some interest in Terr, who has become a young man by now and acquired much Draag knowledge. He escapes into the wilderness, stealing Tivas headphones. ........
