Timothy Treadwell (1957-2003) was not a professional actor in the traditional sense. He was an amateur naturalist and documentarian, known for living in close contact with grizzly bears in Alaska for many years.

His "cinematic career" is inextricably linked to Werner Herzog's documentary, *Grizzly Man* (2005), which extensively utilized his own video footage. In this acclaimed film, Treadwell essentially portrays himself, a complex and controversial character, exploring his dedication to the bears, his theories, and his tragic end.

His style, if it can be so defined, was that of a passionate but unconventional observer, whose life and death became a case study on wilderness and the human relationship with it.
