[4] The producer, Nat Levine, introduced a modern West setting for the film, a dude ranch where horses and roadsters shared the open spaces and the actors dressed in contemporary Western fashions.

The traditional lawman hero was replaced by radio stars and touring entertainers who "happened to foil evildoers in their spare time, rode powerful, intelligent horses, and formed posses composed of guitarists, fiddlers, and harmony singers."

This new modern approach to the Western became a hallmark of Gene Autry and Roy Rogers films made at Republic Pictures in the coming decade.
