In this affectionate send-up of 1940s B-movie Westerns, Rex O’Herlihan is a fast-drawing, fancy-dressing, silver-spurred singing cowboy matinee idol riding through a gleefully offbeat Wild West. With his loyal sidekick, dancing horse, guitar, and spotless wardrobe, Rex brings old-fashioned heroics and movie-serial style to a frontier where the familiar Western formula turns playfully wacko.
