The first section of the film contains an in-joke about Will Hay's real-life career. In 1937 his radio show was faded out to make time for a broadcast by the Prime Minister. Hay was furious and vowed never to broadcast again. A popular outcry led by the Daily Express forced the BBC to apologize before Hay would go back on the air. When Dudfoot's broadcast ends the same way, he says, "The BBC always fade out the best items", and when threatened with dismissal he says, "If only we could get the Daily Express behind us . . . "
Future Bond legend, Desmond Llewelyn, has a bit part as a policeman and is also the headless horseman.
The penultimate comedy featuring Will Hay, Moore Marriott and Graham Moffatt. Hay had made it clear by the time this film was made, that he wished to terminate the comedy partnership.
The only time Moore Marriott played two characters, when acting opposite Will Hay.
