Just found this old sci-fi cartoon on youtube and want to share it with you.
Adapted from Stefan Wuls novel(La Planete Sauvage), this psychedelic sci-fi animated movie depicts a social catastrophe on the far distant alien planet Yagam, run by the Draags, highly intellectual, spiritual, blue-skinned, red-eyed giants. Their household pets are tiny, pink-skinned bipeds called Oms who were brought from the planet Terra. Fed up with the maltreatment from their owners, the oppressed Oms decide to start a rebellion to achieve equality and a better life. But the Draags are determined to exterminate the entire species once and for all. Fantastic Planet was the winner of a 1973 Cannes Film Festival grand prize.
