snuff film

A snuff film is defined by the American Heritage Dictionary as "a movie in a purported genre of movies in which an actor is actually murdered or commits suicide". It may include a motion picture genre that depicts the actual murder of a person or people, without the aid of special effects, for the express purpose of financial exploitation, but that detail is extraneous, so long as it is "circulated  a jaded few for the purpose of entertainment". Some filmed records of executions and murders exist but have not been released for commercial purposes
