A documentary about Nim Chimpsky, the chimpanzee separated from his mother in the early 70s for an experiment looking at whether chimps could acquire language. (His name is a spoof of Noam Chomsky, the linguist.)
Mind-blowing stuff: I don't know how such a selfish, irresponsible set of people got away with what they did to this poor creature.
They brought shame on humankind, and the documentary said more about our species than it did about chimps.
