The documentary Grizzly Man, directed by Werner Herzog, profiles Timothy Treadwell, a man who spent 13 years filming grizzly bears in Alaska. While it appears to be a nature documentary, Herzog uses the film to explore Treadwell's increasingly unstable character and dangerous obsession with the bears. Herzog constructs the film to show Treadwell's authentic yet misguided passion, and to convey his own view that nature is chaotic rather than harmonious. Ultimately, the film is less about nature or Treadwell, and more about using Treadwell's story as a vehicle for Herzog to express his own philosophical worldview.
