 Film rights were sold to the Boulting Brothers for £10,000.Because the play – in which all the characters were British, and the emphasis was more on the enlisted men than in the film – was a hit, MGM retained the title for the film everywhere except in the US and Canada, where the title "Crest of the Wave" was used.Although set on a Scottish island, the movie was filmed in Jersey and at Fort Clonque on Alderney in the Channel Islands, with interiors filmed at MGM's British studios at Borehamwood, Elstree.
