The failure of the original copyright holder to renew the film's copyright resulted in it falling into public domain, meaning that virtually anyone could duplicate and sell a VHS/DVD copy of the film. Therefore, many of the versions of this film available on the market are either severely (and usually badly) edited and/or of extremely poor quality, having been duped from second- or third-generation (or more) copies of the film.
On a Capitol Records 78, Bob Hope and Dorothy Lamour waxed two Jay Livingston-Ray Evans tunes: the romantic "Beside You," a Lamour solo in the film, and a comic-banter ditty named after the movie, although this number was not performed in the picture.
The film contains a number of in-jokes. Bob Hope's character is just saying that he wants to be a private detective like Alan Ladd - when Ladd appears, playing a private detective. Dorothy Lamour's character looks longingly after Bing Crosby for a moment (in their "Road" movies with Bob Hope, Crosby nearly always got the girl) before Hope wins back her attention. There is also a comic reference to legendary music conductor Arturo Toscanini, then considered the greatest conductor in the world, and who at that time was conducting the NBC Symphony Orchestra. (Bob Hope had a radio program on NBC and was soon to make his TV debut on NBC as well.)
The trivia item below may give away important plot points.
Bing Crosby, Bob Hope's long-term co-star and rival in the Road movies, plays an executioner who is livid when he doesn't get to execute Hope's character. Hope fires back saying, "He'll do any kind of role" (at the time, Crosby was a top star - but here he was doing a one-scene cameo.)
