The Gun is a made for television film, of the suspensethriller type, which ABCTV transmitted as a Movie Of The Week on November 13, 1974. It starred David Huffman, Ron Thompson, Richard Bright, Pepe Serna, Lee de Broux, and Stephen Elliott, and was written directly for television by Jay Benson, Richard Levinson, and William Link and directed by John Badham, then a working director of television productions. Levinson and Link were also the producers of the film.
Its last scene, however, depicts a child who finds the gun while it is fully loaded and has none of its safeties engaged. The film shockcuts to black just then, but it is implied that the child has accidentally caused it to discharge a round of ammunitionand been seriously injured, or killed, by the bullet thus fired from it.
