 SPOILER: There was an alternate ending shot for the film. It would  have followed right where the film currently ends, cutting to the  police taking the dead bodies out of the swimming pool. The upside  down body of a person in the clown costume was to be floating in the  pool and when turned over it would reveal Katherine in the suit.  This ending was rejected as being to down beat, the distributors  also insisted more gore be added to the film.
