Heather O’Rourke’s story is a tragic tale, as she died at the very young age of 12. You’d think that since she was only 5 or 6 when she was in Poltergeist that it would be impossible to find any Before They Were Stars material for her.

Here she is working up the courage to jump in a swimming pool. What finally convinces her? Why, McDonald’s, of course.
