Miss Goodall and the Wild Chimpanzees (1965)

Jane Goodall has spent five years observing the chimps in Tanzania (formerly Tanganyika), Africa. One of her discoveries is that they use primitive tools. The film shows the life of the chimps. Retrospective note: This documentary features remarkable historical footage of Goodall, her original camp, and the Gombe chimpanzees. It shows the early years of Goodall establishing the site before it went on to become a world-renowned research center.

Unfortunately the movie Miss Goodall and the Wild Chimpanzees is not yet available on HBO Max.
