"The Exorcist", "The Amityville Horror", "Texas Chainsaw Massacre", "The Conjuring", and "The Blair Witch Trial" are films rumored or marketed as being based on true stories, but at least three have been proven to be purely fictional.
it's The Blair Witch Project, not The Blair Witch Trial.
also, just to elaborate so people know which films are fiction and which are supposedly based on fact: The Exorcist, The Texas Chain Saw Massacre, and The Blair Witch Project were indeed marketed as being based on true stories, but were pure works of fiction only taking bits and pieces of inspiration from various events and urban legends. The Amityville Horror and The Conjuring, however, were based on real people and adapted from reports of alleged hauntings.
incidentally, both films are based on hauntings investigated by Ed and Lorraine Warren, though only The Conjuring actually features them as characters.
Dang it, forgot the last part, thanks for that.
I actually meant withholding some of the info about the veracity of those films as a bit of a joke to keep people wondering, which were and weren't real, but hey if you want turn it into an educational moment that's great.
What I know about the "real" stories behind these films:
"Texas Chainsaw Massacre" is based on two real events, an actual murder by a serial killer and a fantasy that the writer/director had when he was waiting in a long line at Home Depot. He looked over at the chainsaws and thought to himself, "Hey I know how I can get out of here fast."
"The Amityville Horror", I think has been pretty well established as a movie that is very far removed from the facts (most of which it seems were pretty embellished to begin with).
"The Blair Witch Project" is almost purely fiction, without any basis in fact.
"The Exorcist" film is based on a book, which is based on another book, which is mostly just a collection of newspaper articles that covered the "real" story as it happened.
"The Conjuring" I have absolutely nothing to say about, other than what you mentioned.
