The Gorilla Who TalksDVD - 2016
In 1971, graduate student Penny Patterson began teaching sign language to a gorilla named Koko. What started out as a scientific experiment evolved into an intimate friendship, which for almost half a century has challenged the way we think about animals and changed the course of many lives. It is a unique window into this incredible relationship.
