Based on the working schedule in the real life of some actors, the production had to kill a character very early on. When the working print was ready, everybody realized that there is a huge continuity issue there. Extra scenes were shot to explain what has happened to this character, because he appears again by the end of the movie, having survived a neck wound from a knife.
The old bed, on which the lead actress was being held with ropes, was so light that she could probably stand up on her feet and walk away if she tried it.
