Grizzly Man

Werner Herzog built a film from Timothy Treadwell's footage of living among Alaskan grizzlies for 13 summers — until the bears killed and ate him and his girlfriend in 2003. Herzog listens to the audio of Treadwell's death on camera and tells his ex never to listen to it. The real subject isn't bears; it's obsession, delusion, and the indifference of nature. Herzog's narration alone is worth the watch.
