Fantastic Planet.(La Planete Sauvage).Rene Laloux.1973From wiki (what better way to describe things with wiki):
The film depicts a future in which human beings, known as "Oms" (a word play on the French-language word hommes, meaning men), have been brought by the giant Draags to the Draags' home planet, where they are kept as pets (with collars). The Draags are an alien race which is humanoid in shape but ten times larger than humans, with blue skin, fanlike earlobes and huge, protruding eyes. The Draags also live much longer than human beings – one Draag week equals a human year. Some Oms are domesticated as pets, but others run wild, and are periodically exterminated. The Draags' treatment of the Oms is ironically contrasted with their high level of technological and spiritual development
