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 consists of Treadwell's own footage of his interactions with grizzly bears before he and his girlfriend were killed and partially digested by one of them in 2003, and of interviews with people who knew or were involved with Treadwell. The footage he shot was later found, and the final film was co-produced by Discovery Docs, the Discovery Channel's theatrical documentary unit, and Lions Gate Films. The film's soundtrack is by British folk singer Richard Thompson.
Timothy Treadwell spent thirteen summers in Katmai National Park and Preserve, Alaska. Over time, he believed he was trusted by the bears, who would allow him to approach them, and sometimes even touch them. Treadwell was repeatedly warned by park officials that his interaction with the bears was unsafe to both him and to the bears. "At best he's misguided," Deb Liggett, superintendent at Katmai and Lake Clark national parks, told the Anchorage Daily News in 2001. "At worst, he's dangerous. If Timothy models unsafe behavior, that ultimately puts bears and other visitors at risk." Treadwell filmed his exploits, and used the films to raise public awareness of the problems faced by bears in North America. In 2003, at the end of his thirteenth visit, he and his girlfriend Amie Huguenard were attacked, killed, and eaten by a bear.
For Grizzly Man, Herzog used sequences extracted from over 100 hours of video footage shot by Treadwell during the last five years of his life, and conducted interviews with Treadwell's family and friends, as well as bear and nature experts. Herzog also narrates, and offers his own interpretations of the events. In his narration, he depicts Treadwell as a disturbed man who may have had a deathwish toward the end of his life, but also refuses to condemn him for this.
