I remember seeing this as a kid and it blew my mind. The thought of humans as pets shocked me. Amazingly enough this was shown on regular tv (when some tv stations were independently owned). I rarely hear anyone mention it these days, but you should look it up. I think it was the first time I thought about animal rights. Real awareness and action came much later.
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 a hundred times larger than humans, with blue skin, fan-like earlobes and huge, protruding red 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.
