John Mills wore his regimental kilt once more, when he portrayed a Highland Officer in a wartime P.O.W. sketch on the Morecambe and Wise.
Alec Guinness was offered the role of Lt. Col. Barrow, but asked for the role of Maj. Sinclair instead; he then suggested John Mills for the other role.
Joan Hicksoncan be seen among the party-guests at the castle just before Barrow blows his cool. A brief exchange with him appears to be edited out.
Film debut of Susannah York.
The first film of Mark Burns.
The name of the Highland regiment portrayed is never mentioned, although the screenwriter served in the Gordon Highlanders. However, the same regimental tartan (designed for this film) and bonnet badges were worn by the Highland regiment in _Carry On Up the Khyber (1968)_, and so the regiment in Tunes of Glory may well be the "3rd Foot & Mouth."
