During filming of a naked mountain-top scene Emma Cunniffe was left shivering as mist and then hail fell on the set. "It took all day to get the cast, crew and equipment up the peak," said Emma who was in the shot with John Simm. "The weather was great. We stripped for action and the mist came down. There was no way we could just leave so we kept filming. But it started raining. Finally, it was hailing and it was coming down so fast it was like being punched all over. For S&M fans it would have been bliss. But when we saw the bruises it was a disaster for us."
