A sequel, Hillbilly Blitzkrieg, was released later in 1942 and also featured Duncan and Kennedy.

The comic strip's characters Barney Google and Sparkplug the horse do not appear in the film.

Envious of the pay of $30 per month and free khaki britches and gold buttons of his friend Don Elbie, Snuffy Smith joins the U.S. Army with his dog Mr. Carson concealed by an invisibility potion.

His company first sergeant is Ed Cooper, a former revenue agent who had unsuccessfully attempted to locate and destroy Snuffy's still.

A pair of fifth columnists hope to steal the rangefinder but are defeated by Snuffy's wife Lowizie, his invisible dog and his hillbilly neighbors.
