"Project Nim" tells true story of ground-breaking primate experiment

This insightful documentary tells the true story of a chimpanzee raised by scientists in the 1970s as part of a landmark study into communication.

In 1973, a group of American primatologists set out to discover if a chimp named ‘Nim Chimpsky’ who was raised like a human child could learn to communicate through language.

The story of Nim's amazing journey through human society and the relationships he forms with those around him make for a brave and unsentimental biography.

James Marsh and the Oscar-winning team behind Man on Wire tell this extraordinary story through previously unseen archive footage and interviews.
