Jane Goodall Documentary Highlights Her Research's Breakthrough Moment (Exclusive Video)

Brett Morgen directs the National Geographic film, which uses over 140 hours of previously unseen footage.

The breakthrough achievements of Jane Goodall are outlined in the documentary Jane.

Directed by Brett Morgen (Kurt Cobain: Montage Of Heck, The Kid Stays in The Picture), the National Geographic film uses over 140 hours of previously unseen footage to chronicle the work of the pioneering British primatologist, as she studied chimpanzees in the wild in Africa. The Hollywood Reporter's exclusive clip of the doc previews her first experiences in Gombe, Tanzinia in the 1960s, and the major moment when she realized that these animals, like humans, use tools.

"My observations at Gombe would challenge human uniqueness, and whenever that happens, there is always a violent uproar," she says in the clip. "There were some who would try to discredit my observations because I was a young, untrained girl, and should therefore be disregarded."

Abramorama releases Jane in limited theaters on Oct. 20. It debuted at the Toronto International Film Festival last month and screens next at the New York Film Festival.
