We filmed this in a place in Scotland called Ballachulish. Try saying that after a couple of drinks. We used three Super-8 cameras, which we passed round on a tray, and I allowed anyone to film who fancied it. It was February, 1990, the so-called "week of the big snow." Robert said he had never been so cold and because of the freezing temperatures the cameras, which worked by battery, kept running low. It meant I only got a few seconds of film at a time. The evening, as you see, finished with a fantastic snowball fight.
