This isn't the first attempt to tell the "real," story (see here or here). Only the most recent.
Trivia tidbit: Our very own chief blogger Chad Garrison was interviewed by the brothers Booth for this movie, after having written a feature story on the north St. Louis County house where the possessed child stayed for a while ("Hell of a House," 2005). However, Garrison didn't make the final cut. He declines to speculate why.
What's next for the Booth Bros? A little more St. Louis - area ghost action, according to what Christopher Booth recently said in an interview:
We have a new film coming soon called 'Soul Catcher' based on a true story. Part of the film was filmed at Lemp Mansion, which is very active. There was a boy who was kept in the attic . He was known as the 'monkey faced boy'. He was disfigured due to down syndrome. People see his spirit in a window sometime. We found a young boy with a disability to play this young boy so we could capture the real emotions. We had Native American psychics with us as we investigated the house. A mist appeared above the head of one of the psychics. It formed a face...it pulled together and looked like a face with a mask or a bag on it, this was caught on film. So, we wanted to tell his story.
