Awesome late 80s french horror movie '3615 code pere noel' i think it's 'Game Over' in the us. Anyway, great movie, saw it as a kid and it scared me for years. If you haven't seen it I definitely recommend it. Hard to find. I have it on VHS and made a dvd copy of it, but it took me years to find the VHS copy. you can watch the whole movie on youtube.
