Jane Goodall, one of the most famous environmental and animal activists, is the subject of a new documentary covering her inspiring life and the constant efforts she makes to help "spread hope for future generations."


Titled "Jane's Journey," it follows the 75-year-old as she travels around the world as a U.N. Messenger of Peace — from her home in Bournemouth, England, to the shores of Lake Tanganyika in Tanzania — the latter being the site of her groundbreaking research into chimpanzee social and family life.


The film debuted last year in Germany, but is only now being shown in select U.S. theaters. One reviewer called it "a beautiful tribute to Dr. Goodall's accomplishments."


One celebrity who immediately agreed to become part of the project was Angelina Jolie, who has teamed up with Goodall before on charity projects. "I was delighted when she told me she would be excited to be a part of the film," Goodall told People Magazine. "Sometimes, caught up in the moment, people promise to give their support but don't, or can't come through. That was not true with Angelina."


'Jane's Journey," which premieres in 500 theaters around the U.S. on Sept. 27, will be an live interactive event — with Goodall answering audience questions. Musician Dave Matthews will also make an appearance to presumably perform and to discuss his time in the field with Goodall. Tickets can be purchased here
