When it comes to horror movies, it’s always interesting to learn how the moviemakers came up with their endings — especially endings as ambiguously terrifying as that of The Blair Witch Project.
The first ending kept the audience off balance; it challenged our real world conventions and that’s what really made it scary.
Sanchez said that apparently they came up with the ending when they were almost done with the rest of the movie.
The ending to The Blair Witch Project (spoilers, obviously), consists of the last two characters standing, Heather and Mike, running through a dark house looking for their friend Josh, who they can hear calling from somewhere in the building.
