The Blair Witch Project
Blair Witch Project follows three documentary filmmakers who travel to the Black Hills of Burkittsville, Maryland to find the Blair Witch and get her to clean up all of the discarded toilets that are cluttering up her lawn.
This was the independent movie from 1999 that became an international sensation. One of the main reasons this movie became so huge was the viral marketing campaign that preceded it. It was also the movie that was credited with causing the found footage boom that we are still experiencing today.
