Written and directed by Daniel Myrick and Eduardo Sánchez, The Blair Witch Project (1999) was filmed entirely in Maryland and was the first “found footage” horror film. It made over $248 million worldwide on a $60,000 budget.
The Blair Witch Project was presented as a real documentary project that went wrong when its three filmmakers disappeared in the woods near Burkittsville, Maryland. Much of the movie’s first 13 minutes were filmed in and around Burkittsville, a real town in Frederick County.
Burkittsville’s sudden notoriety annoyed its inhabitants, and souvenir hunters repeatedly stole the town’s iconic sign. The wooden welcome sign shown in the film has been replaced by a more fashionable blue one.
A middle-aged man who told the story of a (fictional) series of child murders in the 1940s (played by Jim King) outside a grocery store, was actually filmed at Stups Market in nearby Adamstown.
The convenience store at 5550 Mountville Road was, at the time of filming, called Adamstown Village Market. In this screenshot, you can see the store’s posts, brick corner, and house with a white porch across the street.
