 When shooting on location in Norway, a fierce snow storm hit the  hotel where cast and crew were staying. This would have normally  halted filming, but director Irvin Kershner (qv) thought these  weather conditions were an excellent opportunity to film the scene  where Luke wanders through the snow after escaping the Wampa cave.  He did this by sending Mark Hamill (I) (qv) outside into the cold,  while he and the cameraman stayed and filmed inside the hotels  front hall.
