The Blair Witch Project was an anomaly in storytelling and movie promotion when it made its way into the public consciousness in 1999. Not only did filmmakers Eduardo Sánchez and Daniel Myrick promote the horror film as real-life found footage - going so far as to make the three lead actors hide until after the premiere - they crafted a movie that left audiences with more questions than answers. Many viewers left the theater unsure as to whether they had just witnessed a snuff film of sorts, especially since multiple Blair Witch legends are woven into history, often based on real people.
As a result of the cultural impact and long-standing unanswered questions, multiple The Blair Witch Project theories exist. Even today, new theories pop up all of the time, offering evidence connected to the 2016 sequel Blair Witch or expanding upon possible truths proposed more than a decade ago. Some of the most popular and intriguing theories about the film hope to uncover the truth behind what happened to Heather (Heather Donahue), Josh (Joshua Leonard), and Mike (Michael Williams).
