 SPOILER: Additional death scenes were filmed after the movie was  screened for test audiences: the death of Martin (who is not killed  in Simon Hawkes novelization of the film); the double impalement of  Annette and Steven (neither of whom are featured in the  novelization); and Sissys death was actually filmed, rather than  just showing her being pulled out of the window and her head found  later, as was originally in the film.
