John Steineck's novel The Wayward Bus was retranslated into pop-entertainment terms for the screen. Most of the story takes place on the charter bus owned by driver Rick Jason. Travelling slowly through a treacherous California mountain region, the passengers -- including Jason's spiteful, alcoholic wife Joan Collins-- undergo a variety of life-altering experiences. The journey has its most profound effects upon an iconoclastic travelling salesman (Dan Dailey) and lonely stripper (Jayne Mansfield). This is one instance in which the oblong CinemaScope lens is inappropriate to the intimacy of the story.
