Wayne Morris' last movie before he went off to World War II. He would go on to become an ace U.S. Navy fighter pilot. He was awarded four Distinguished Flying Crosses and two Air Medals. He wouldn't appear in another film until 1947 in El valle de las sombras (1947).
Willie Best was given on-screen credit in the original theatrical trailer. On the film, his name does not appear in the opening credits despite his prominent role in the film (although he is properly included in the cast list at the end, billed eighth).
Warner Brothers made this film, a B-Grade "quickie," in hopes of emulating the success of the previous year's Paramount horror comedy hit, El castillo maldito (1940). That film was among Bob Hope's biggest box office hits, and co-starred him with Paulette Goddard, Anthony Quinn and Willie Best (who plays Clarence in Smiling Ghost) as Hope's knock-kneed, wise-cracking man-servant, but results were so pitiable there was no comparison.
