Sheriff "John T." – played by John Wayne – finds himself stuck with an inebriated deputy, “Dude” (Dean Martin), at precisely the moment that local property owner "Burdette" (John Russell) is demanding the release of his violent brother from jail. Fortunately, a friend, "Pat" (Ward Bond), arrives with his wagon train, and along for the ride is "Colorado" (Ricky Nelson), someone who knows how to handle a gun. Initially unwilling to get involved in another person's problems, circumstances lead him to change his stance, giving Duke a fresh partner. Just when he believes things couldn’t possibly deteriorate further, a stagecoach pulls into town with a faulty wheel and "Feathers" (Angie Dickinson), a card sharp who seems to know exactly how to push the sheriff's buttons and drive him crazy. As the situation escalates, they seek refuge in their jail for a musical interlude featuring Martin, alongside some sharp-tongued moments from what feels like the true standout of the movie: Walter Brennan. He portrays "Stumpy," a grumpy old man assigned to watch over their prisoner while preparing dinner. Wayne and Martin have good chemistry together, although Nelson’s performance is somewhat stiff; however, his presence does provide some visual appeal, as well as an energetic version of “Cindy” that even gets Wayne moving. The film steadily progresses toward a lively and explosive conclusion, complete with impressive action sequences and a precisely fired sawed-off shotgun to finish things off. It's a dependable narrative featuring interesting characters and is definitely worth seeing – even if westerns aren’t usually your preference.
