Fantastic Planet

A band of humans -- known as Oms -- are kept as domesticated pets by an alien race of blue humanoid giants called Traags in director Rene La Loux's animated sci-fi classic, said to be based on the Soviet occupation of the Czech Republic. The story centers on an Om named Terr, who escapes his subjugation with a Traag learning device and eventually uses it to educate other Oms and incite them to revolt. The film nabbed the Grand Prix at Cannes.
