Grizzly Man

Grizzly Man is a 2005 documentary film by German director Werner Herzog. It chronicles the life and death of bear enthusiast Timothy Treadwell. The film includes some of Treadwells own footage of his interactions with grizzly bears before 2003, and of interviews with people who knew, or were involved with Treadwell, as well as professionals dealing with wild bears.

Herzog used sequences extracted from more than 100 hours of video footage shot by Treadwell during the last five years of his life. He also conducted and filmed interviews with Treadwells family and friends, and bear and nature experts. Park rangers and bear experts commented on statements and actions by Treadwell, such as his repeated claims that he was defending the bears from poachers. Park rangers noted that there had never been a recorded incident of poaching at this national park.As another example, Treadwell claimed he had gained the trust of certain bears, sufficient to approach and pet them. Park rangers pointed out that bears are wild and potentially dangerous animals given that, Treadwell was lucky to have survived so long as he did without being mauled. One park ranger suggested that the bears were so confused by Treadwells direct, casual contact that they werent sure how to react to him. Other park rangers point out that the bears were not threatened by poachers, but Treadwells actions put them at real risk of harm and death. By familiarizing them with human contact, he increased the likelihood that they would approach human habitation seeking food, and cause a confrontation in which animal control would have to kill them. ........
