Bear 71 was a female grizzly in Canada’s Banff National Park and it’s the name of an unusual new documentary about her life. For several years, surveillance cameras captured Bear 71’s movements through the park and the nearby town of Canmore, Alberta. Filmmaker Leanne Allison used that footage and a wealth of information collected about Bear 71 and other park animals as the basis of a new kind of storytelling experience. Bear 71, the documentary, marries traditional film making to an interactive web site that lets viewers choose the elements they wish to see and even enter the story themselves.
