This movie appears to be about Nazis, conspiracies, and weapons, but really it's about a troubled romance that this stuff gets in the way of. Hitchcock crafts a taught story around this MacGuffin. Grant is moody rather than quick witted, Bergman is Bergmanesque, and Rains is excellent as always. Not much mystery in the story, but the elements all work well.
Well made but I had issues with the on-screen chemistry. I had trouble with the spy-agent relationship. Claude Rains was awesome as usual, but maybe I just wanted Grant to play the same Cary Grant character he usually does. Still, a good, complex film. AMRU 3.5.
