The six minute audio recording of "Grizzly Man" Timothy Treadwell and his girlfriend being eaten alive by a bear that director Werner Herzog felt was too gruesome to include in his documentary.
There's a (probable)
fake two minute version all over the internet. Some people insist it's an authentic two minute slice of the real audio that some park ranger nabbed on his phone during the investigation. I'd give it a 10% chance of being authentic, if not would be an amazing reenactment by the actor who played Timothy whose voice is uncannily like Timothy's. His screams however aren't
truly blood curdling and the looping fake bear noises are obviously dubbed in.
It's probably the most extreme audio ever recorded and given how many humans have also been gruesomely eaten alive by animals in history (millions?). That's why it's very interesting, it's an important part of human history and why we evolved the way we did to avoid these predators.
