That was bloody close. Before the planned D-Day landings the British Government is spreading disinformation to distract German attention from the Normandy beaches. Two intelligence officers, Colonel Logan (Cecil Parker) and Major Harvey (John Mills) are running the operation but they are initially unable to devise such a plan. One night at the theatre in London Harvey sees an actor do a convincing impression of General Bernard Montgomery. He is M.E. Clifton James, in the army Pay Corps stationed in Leicester and the officers hire him to act as a decoy – playing Montgomery doing a tour of North Africa. After studying him and meeting him, he is dispatched to Gibraltar where the British anticipate that a known German agent Karl Nielson (Marius Goring) posing as a businessman will encounter him and hopefully inform Berlin. ‘Monty’ is accompanied by Harvey who is promoted to Brigadier to act as his aide de camp. When the British learn that the Germans are moving their panzer divisions away from Normandy this ‘Monty’ is sequestered in a North African house until it is safe to return him to his original job but the Germans have other ideas … Adapted from the autobiography of M.E. Clifton James by Bryan Forbes (who plays a crucial role in the penultimate sequence) this is a spry and suspenseful account of Operation Copperhead. Told efficiently, with James playing himself – and Monty! – it moves quickly and two scenes in particular are handled very well by director John Guillermin: when Nielson meets Monty it transpires it’s for the second time – a shocker; and the inevitable kidnapping. With a brisk score by John Addison and a good turn by Mills, one of the many in the Fifties that encapsulates his particular brand of British masculinity, this is an entertaining account of yet another Believe It Or Not from WW2: the gift that just keeps on giving, especially when you realise that the man who actually recruited Clifton James was none other than … David Niven! There are good supporting roles for Michael Hordern, Leslie Phillips with James Hayter, Sid James and Sam Kydd down the ensemble.
