The much-loved series which was loosely based on the life of James Capen Adams who trained bears in California in the mid-19th Century, tells the story of a mountain man who is forced to live in the wilderness after being wrongly accused of murder. While on the run, he adopts an orphaned grizzly bear and names him Ben.
The film became the seventh high-grossing film of 1974 and the NBC network aired a TV series of the same name, which ran from 1977 to 1978, BBC News reports.
