From the saloon standoff at the end of Shane to the cemetery showdown at the end of The Good, the Bad, and the Ugly, there are plenty of exciting shootout sequences in classic Western movies. Shootout scenes are one of the most prevalent tropes of the Western genre, along with bar fights, cattle drives, and train robberies. Almost every Western movie culminates in a high-octane gunfight between the heroes and villains. Even the most subversive anti-Westerns, like The Great Silence and McCabe and Mrs. Miller, can't stay away from shootouts in their final acts.
