May I respectfully disagree with many of the posters here, who, knowing that Cooper had cancer while he made this film, claim that his under-played performance proves that he lacked the necessary vigor to do the character of the beleaguered husband justice. Quite the opposite! Cooper, who was famous for under-acting, most perfectly portrays a long-loving long-suffering husband who understands why his wife suspects him, but has decided (until the end) not to tell his wife the truth. If you watch his performance carefully scene-by-scene, you will see how skilfully he manipulates the audience: Cooper makes us believe he might be guilty or ... if you wish, might not. A tour-de-force of keep-them-guessing acting in the classic Hitchcock manner. Is he evil out isn't he? Much credit must be given here to the masterful direction of Michael Anderson, another neglected English director of exceptional talent with camera and actors who ended up doing too much minor work in Hollywood, as well as the superb contribution of Berlin-born cinematographer Erwin Hiller, a protege of FW Murnau and Fritz Lang.The B&W photography is astonishing. A plot full of improbabilities, yes, and the music keep spelling out what we can see, but all in all, an excellent job of suspense in the glossy English manner.
