the shocking climax

Our group Mad dogs are aware that at the end of the film there is a shocking climax with a man under the bed and the girl starting to lie down and then we see them both parallel with each other. This idea came from "One hour photo" and we wanted it to seem real and that would be in a real thriller film. We think as a group this is a very strong image that is given out but this will be solved throughout the rest of the film.
