Poltergeist
I know many watch the same programs I do,
And I knew of paranormal activity plaguing the making of the Exorcist , On poltergeist , I was unaware as I am sure
Many other's were , The studio thought using plastic skeletons would be pricey so to cut corner's they actually
Used real skeletons on the set unbeknownst to the actor's and actresses, After they suffered many expensive mishaps
On the happened that plastic does not seem so expensive now!
Sadly even though this was a movie, Contractor's do build over cemeteries and only move the marker's.
