Great video seen it a while ago.
If you want to see another documentary on the same lines try and watch the Werner Herzog's production "Happy people.....a year in the Taiga", 90 minutes of supreme documentary making and narrative by the master at the top of his game, was readily available on You-Tube at one time as the full 90 minutes, but now i can only find snippets on there and was unable to post a link to the forum, maybe someone more techno-savvy can find te full length version and do the honours? It is a must see documentary IMO, blew me away the 1st time i watched it.
