The LAT has a feature story on Burkittsville, Maryland. Ten years ago, Burkittsville was (partially) the setting for The Blair Witch Project, and the town has been dealing with fallout from that ever since.
…their town was in a movie — actually just the graveyard and a two-second shot of one of the gray and blue welcome signs posted at the four entrances.
The moral of this story, according to the LAT writer:
Never let Hollywood make a horror movie in your town.
The very next paragraph after that statement begins:
The independent filmmakers never asked Burkittsville’s permission.
