Movie Description
Koko: A Talking Gorilla is a 1978 documentary directed by Barbet Schroeder that focuses on Dr. Francine 'Penny' Patterson and her work with Koko, the gorilla Patterson claims to have taught to communicate with humans using symbols taken from American Sign Language. The film was screened in the Un Certain Regard section at the 1978 Cannes Film Festival.
The film introduces us to Koko soon after she was brought from the San Francisco Zoo to Stanford University by Dr. Penny Patterson for a controversial experiment-she would be taught the basics of human communication through American Sign Language.
