Released in 1999, The Blair Witch Project became a genuine sensation. The horror movie -- following three student filmmakers attempting to make a documentary about an urban legend -- was presented as a found footage film. Although it wasn't the first of its kind -- both Orson Welles' The Other Side of the Wind and the controversial cult classic Cannibal Holocaust predate The Blair Witch Project -- the success of the film at the turn of the century set off a new wave of similar films.
