Mrs Masson's biggest joy is that the film will throw renewed limelight on her adored heroine. Christine Granville, who was Polish-born, was awarded the George Medal, OBE and Croix de Guerre for her outstanding bravery working as an allied spy in Poland, Hungary and France.
"She had more ribbons than a general," Mrs Masson said. "She exuded a kind of extraordinary magic - something that set her apart from every other person I've ever met. There was some magnetic force emanating from her."
In the annals of European resistance, Granville is known as Churchill's favourite spy because her information about a Nazi tank build-up on the Russian border supposedly enabled the war leader to warn his Soviet counterpart, Stalin, of an impending attack.
