Found footage is a plot device in pseudo-documentaries in which all or a substantial part of a fictional film is presented as if it were discovered film or video recordings. The events on screen are typically seen through the camera of one or more of the characters involved, often accompanied by their real-time off-camera commentary. For verisimilitude, the cinematography may be done by the actors themselves as they perform, and shaky camera work and naturalistic acting are routinely employed. The footage may be presented as if it were "raw" and complete, or as if it had been edited into a narrative by those who "found" it.
