grace

who is the girl in the picture? is it an actress? someone in the crew? a random person? or is grace really real? lol. did this guy have someone make a "movie" within a "mocumentary" within a movie based on real accounts or is the story completely fake? i know the "micheal" in the film is an actor, but is it based off a real person? i really enjoyed the movie. the movie left me wanting grace to be real.
