The frightening, low-budget, found-footage horror movie was written and directed by Daniel Myrick and Eduardo Sanchez, and featured an unknown cast who used their own names in the film.
The Blair Witch Project 15 years on: The horror movie that changed everything
It became the first of its kind in Hollywood due to its commercial success and viral online campaign, which was created to make the production look like a real documentary. The Blair Witch website with details on the made-up mythology still exists.
And the clever campaign worked on some gullible and vulnerable viewers. We remember witnessing real tears of fear being shed by some audience members in the cinema (and definitely not ours...).
It purports to be a documentary shot by three inquisitive, daring, and at times daft students investigating the local Blair Witch legend in the Maryland forest.
