In reply to Dan Bailey - UKHillwalking.com:
A couple of years ago I was vaguely considering making a cheesy ultra low budget horror movie about the grey man offing a load of climbers & walkers.
Climbers arrive, hear and dismiss ominous mutterings from deer stalkers about strange sights, walking group going missing on Ben Macdui etc.
First death was to be a mysterious figure rearing up and pushing a climber off the top of squareface. Night or two later (after everyone has decided it was just an accident) you would get the stereotypical victim pulled out of tent scene.
Scene: The howff under dividing buttress, or maybe the one over at garbh coire. Two climbers (probably couple) settle in for the night and bitch about midges. Suddenly a huge carpet covered arm reaches in, pulls one of them out, the other is sprayed with blood and organs. Flees. Doesn't get far.
A few more things of that ilk with a last stand/slaughter at bob scotts or slugain howff.
Other things to look out for: Gratuitous disregard of geography implying that all these places are both 3 days walk from safety and half an hour away from one another. Random seasonal changes and other continuity errors. That kind of thing.
Maybe I should get my arse in gear and write the script.
