On the set of this film, Oliver Hardy met his future wife, script supervisor Virginia Lucille Jones.
Stan Laurel spoofs Harpo Marx when he strums on his bed spring and plays it like a harp. Marx was famous for playing the harp in (almost) every Marx Brothers movie; in fact, he dubbed Stan's playing in this film.
This is Stan Laurel and Oliver Hardy's only non-Hal Roach-produced film in which Stan had a hand in the writing and editing (as he had in the Roach films).
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 dubbed from second- or third-generation (or more) copies of the film.
The plane that does all the fancy flying at the end of this movie is a 1928 Travel Air 6000, better known to some as a Curtis-Wright 6-B (Curtis-Wright acquired the Travel Air company in 1931). It is an American plane, despite being painted in this movie with French roundels on the wings.
