Whoever uploaded this to YouTube claims 1952, but it’s definitely a 1953 flick.
The fil-um moves CS Forester’s story from the First World War to the Second World War and we have Hollywood’s Jeffrey Hunter as a Canadian.
But it’s a cracking piece of cinema from Roy Boulting. Incredible battle sequence from 25-minutes onward. Bernard Lee, Victor Maddern and Sam Kydd play their character roles with the humour and sangfroid expected from a black-and-white British war film. Well worth watching before YouTube delete it.
