In 1960, a young English woman away from home for the first time became an assistant to Dr. Louis Leakey, with Leakey eventually sending her to Gombe Stream National Park to gather data on the local chimpanzee population. Her name was Jane Goodall, and the trip was documented in National Geographic's popular doc Miss Goodall and the Wild Chimpanzees. Here, director Brett Morgen (Kurt Cobain: Montage of Heck) delves through leftover, lost footage from Goodall's first journey into the jungle, creating a rich experience of this remarkable researcher.
