Interesting, not so much because of what is on the screen, but because of when it was made and the obvious wartime strictures that forced it to use a variety of painted backgrounds and models. Good performances that are both interesting and amusing.
Wonderful story and acting....people compare this to Hitchcocks The Lady Vanishes but I think it stands on its own with Carol Reed's direction, lots of comical bits and Rex Harrison just shines in his first major role as a British spy. Thoroughly enjoyable!
