Have John Mills and David Niven ever been in the same film? I started pondering while this was on. Surely some later epic, Oh What a Lovely War, A Bridge Too Far, something like that. Turns out yes, but only one. Mills has a cameo as a cab driver in Around the World in 80 Days.
It was adapted (pretty obviously) from a 1953 stage play by Campbell and Dorothy Christie, by John Hunter, for Romulus Productions. (The Christies also wrote the stage play for Grand National Night.) Officer David Niven responds rather coolly to a charge of fraud after he's borrowed some army money, an allegation made against him by Colonel who hates him, played by Allan Cuthbertson. But as the court case proceeds, with contributions from fellow officer Noelle Middleton and bitter wife Margaret Leighton, she shifts the blame back on to her husband.
So obviously entirely talky but with an intriguing plot worked through.
The three stars were BAFTA nominated as was the film.
Good other contributions from Victor Maddern as the sergeant who keeps getting demoted (who I probably recognise from The Dick Emery Show!), Geoffery Keen (president of jury, most notably from The Angry Silence), Raymond Francis (Niven's mate), Maurice Denham, Laurence Naismith, Stuart Saunders (heavy-booted sergeant).
Desmond Dickinson photographed, Ralph Kemplen edited.
Didn't really know Middleton, though have seen her in The Vicious Circle (if that doesn't contradict myself too much), starring John Mills, which funnily enough takes us full circle.
