Found footage is a genre of film making, especially horror, in which all or a substantial part of a film is presented as discovered film or video recordings, often left behind by missing or dead protagonists. The events on screen are seen through the camera of one or more of the characters involved, who often speaks off screen. While the genre dates back at least as far as 1980's Cannibal Holocaust, it was popularised after the release of films such as The Blair Witch Project (1999), Paranormal Activity (2007) and Cloverfield (2008)
