Tennyson called nature “red in tooth and claw,” but that warning didn’t keep Timothy Treadwell from living among the grizzlies of Alaska for thirteen summers–until one of them killed him and his girlfriend. Werner Herzog’s 2005 documentary Grizzly Man tells Treadwell’s story and raises the issues of what happens when we ascribe human motives and characteristics to animals and the ways in which we all attempt to stake out our own territory in an indifferent world.

Incredible bumper music by John Deley.

Herzog’s most recent book The Future of Truth (2025) is a series of essays about what constitutes truth and the threats truth faces in our age of AI and deepfakes.
