Poltergeist

The movie Poltergeist features a scene in which skeletons pop up from their coffins in a family's backyard. Allegedly, the special effects department used real human remains for some of the shots and thus The Poltergeist Curse was born. Dominique Dunne, who plays the eldest daughter in Poltergeist, was strangled to death by her ex-boyfriend just a few months after the film premiered. During the filming on the third Poltergeist film, actress Heather O'Rourke, 12, died of septic shock from an undiagnosed condition.
