Lisa Daniely is quite engaging as the eponymous character in this post-war homage to the sweethearts whose songs lifted many an heart during the hardships of WWII. She is working in a small North African bar that finds itself controlled by the British, the Nazis, then the British again - with both sides aware that she is the source of the legendary song, and with both equally aware of her enormous propaganda value. Amidst all this toing and froing, she meets and gradually falls for "Steve" (Hugh McDermott) before being recaptured by the Nazis and taken to Berlin where she is encouraged to make broadcasts in English to smash morale. Nobody will sing this song like Marlene Dietrich, but Daniely makes a decent fist of her frequent renditions - in English and German - and her porcelain-like features and delicacy of performance engender a sense of her vulnerability as she is but a pawn in a dangerous game. McDermott could never be described as versatile and it's all grin and smart-assed quips from him here too. The production has been nowhere near a desert, but as wartime feel good films go this is at the more entertaining end with just enough menace from some nasty Nazis to remind you that it could all have been true!
