Grizzly Man part 2
Or maybe Grizzly Man the Prequel since the events of this documentary happened before Treadwell died.
But it has a lot of the same elements. People with strange living and sexual arrangements, an undo fascination with wild animals, show business, and the death of two people and the animal who killed them, and yes, the documentary followup.
What is it with sexually ambiguous people, wild animals, and show business?
