Grizzly Man (2005) is an American documentary film by German director Werner Herzog. It chronicles the life and death of bear enthusiast Timothy Treadwell and the death of his girlfriend Amie Huguenard at Katmai National Park, Alaska. The film includes some of Treadwell's own footage of his interactions with brown bears before 2003, and of interviews with people who knew or were involved with Treadwell, in addition to those of professionals who deal with wild bears. Treadwell and his girlfriend, Amie Huguenard were both from New York. He had been studying bears for several summers at the park. They were attacked and killed by a bear there on October 5, 2003. Treadwell's footage was found after his death. The couple's remains were discovered by a pilot. The bear that killed Treadwell and Huguenard was later encountered and killed by the group who retrieved the pair’s partially consumed remains. An audio recording of the attack was captured by Treadwell's camera, but has never been released. The final film was co-produced by Discovery Docs, the Discovery Channel's theatrical documentary unit, and Lions Gate Entertainment. The film's soundtrack is by British singer-songwriter and guitarist Richard Thompson. Synopsis 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 Treadwell's 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 Katmai National Park. Treadwell also claimed that 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 as long as he had without being mauled. One park ranger suggested that the bears were so confused by Treadwell's direct, casual contact that they were not sure how to react to him. Other park rangers note that the bears were not threatened by poachers, but that Treadwell's 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 humans would kill them. In
