Natural Born Killers (1994)

Oliver Stone's satirical indictment of media glorification of violence was itself accused of glorifying violence. The film was linked to at least a dozen copycat murders worldwide, including the Columbine shooters who reportedly discussed it. Author John Grisham sued Stone (unsuccessfully) after a friend was shot by teens who had watched the film repeatedly. The irony — a film about how media creates killers being blamed for creating killers — proved its own thesis.
