The Blair Witch Project is a 1999 American supernatural horror film written, directed and edited by Daniel Myrick and Eduardo Sánchez. It is a fictional story of three student filmmakers—Heather Donahue, Michael C. Williams, and Joshua Leonard—who hike into the Black Hills near Burkittsville, Maryland, in 1994 to film a documentary about a local myth known as the Blair Witch. The three disappear, but their equipment and footage are discovered a year later. The purportedly "found footage" is the movie the viewer sees.
