Rio Bravo is a 1959 American Western film directed and produced by Howard Hawks and starring John Wayne, Dean Martin, Ricky Nelson, Angie Dickinson, Walter Brennan, and Ward Bond. Written by Jules Furthman and Leigh Brackett, based on the short story "Rio Bravo" by B. H. McCampbell, the film stars Wayne as a Texan sheriff who arrests the brother of a powerful local rancher for murder and then has to hold the man in jail until a U.S. Marshal can arrive. With the help of a lame old man, a drunk, and a young gunfighter, they hold off the rancher's gang. Rio Bravo was filmed on location at Old Tucson Studios outside Tucson, Arizona, in Eastmancolor, with film processing provided by Technicolor.

Jules Furthman was an American magazine and newspaper writer before working as a screenwriter. Pauline Kael once wrote that Furthman "has written about half of the most entertaining movies to come out of Hollywood "
