Chatterbox
While shooting a western on location, a Hollywood "cowboy" star--whose offscreen image is exactly the opposite of his onscreen one--is saved from disaster by a gregarious local girl. She winds up becoming not only his leading lady in the movie but, because of a set of nutty offscreen circumstances, his fiancé in real life.
