Trivia: When Tina is dragged along the ceiling as she is killed. To do this they built the room out of metal with 3 rotating axes. They just covered the metal with scenery walls, to make it look like a regular bedroom. They bolted the camera, and every piece of furniture to the floor of the room. Nick Corri, who plays her boyfriend was similarly harnessed to the floor. As Tina is dragged across the ceiling the room is upside-down and she is simply rolling around on the ceiling of an upside-down room. Since the camera and Rod are both strapped to the floor of the room it creates the illusion that she is flying around the room.
