In reply to Only a hill:
I haven't seen 'The Cairngorms in Winter with Chris Townsend', just the trailer on Youtube- Certainly worth watching for Terry Abraham's photography.
On the subject of Scottish mountain films, last year I met a film maker, James Urquhart, up at the Crask Inn.
He had set out, the year previous, to walk and film the experience of a munro round on foot, unsupported. In the event, the trip took him into a second year, with a lay off over the winter.
He has a website 'Beyond the Mountains' and there are several trailers on vimeo/youtube. Here's one of them:
I got the impression that he's using the format of a munro round, not to promote his personal accomplishment, but to look outwards to the varied mountain environment and people encountered on such a journey- Hence his website's name 'Beyond the Mountains.
Given the ammount of kit he was lugging - camera and all- and the demands of filming and editing on the move, it's not surprising that his journey went into 2 years.
I've no commercial interest in his project, but put this up on the UKC forum as I feel he deserves a wider audience.
