The following ten films feature men (not many women here, it has to be said) who take on nature and don't fare too well. If they do come out alive, they're likely to be very damaged and scarred for life, both physically and mentally. Mountains and rivers want to devour us, animals want to eat us, and violence is everywhere, as, away from the safety of civilisation, we turn on each other. So, you fancy it? Abandoning your home comforts, upping sticks and going on a primitive voyage of self-discovery? Us neither. Easier to just watch these instead.
