Well I am putting this in after just watching the Revenant. I took another look at this film which scared the heck out of me as a kid. I can remember watching this on television, weekend days at least 2x. It is a horrifying story, but keeps your attention.
The persistence and human will portrayed are somehow inspiring.
The weird old boat and hunting party that drag along add to the weirdness that makes this memorable. This story of Hugh Glass has been told many times, I guess. The fear of native Americans on the frontier drives this plot of this film too. Portrayals like this trained me how to think in ways.....which are very hard to overcome.
Having spent a lot of time in the woods, seeing bears (black only) and having spent time in the woods in winter, this story is very hard to believe. I can't imagine trying to fight a grizzly. As we all know now, watching survival shows, just getting water that doesn't make you sick is a big deal. You could die from something small like that let alone mortal wounds, no proper clothing, knives and hunting implements.
This film seems to focus on the psychological, but its the tools and skills that would allow someone to survive.
