Gun the Man Down is a 1956 American western film directed by Andrew V. McLaglen and starring James Arness and Angie Dickinson in her first leading role.

Gun the Man Down remains arguably most notable for containing actress Angie Dickinson's first starring (credited) role.

Wayne introduced the series in a film clip shown immediately before the initial episode while dressed in cowboy garb and speaking directly to the camera.

Arness had earlier portrayed the Frankenstein-like "carrot monster" glimpsed in flashes and the conclusion of Howard Hawks' 1951 version of The Thing.

Except for a gag cameo in the Bob Hope comedy Alias Jesse James, it was his final theatrical film before devoting himself exclusively to television.
