Alfred Hitchcock's pre-war spy thrillers are interesting because on the one hand they're romps and on the other hand they're designed to subtly push the British public against Germany in a time when the film cannot openly call the bad guys German. This tonal dialectic really worked for us in The Man Who Knew Too Much (1934, Spine 643) and The Lady Vanishes (1938, Spine 3), but falls a little flatter in The 39 Steps (1935, Spine 56) and Foreign Correspondent (1940). Here the unevenness is more noticeable, and that's because bubbling just below the surface is a fight between Hitchcock's desire to make a normal Hitchcock movie and producer Walter Wanger's desire to make an up-to-the-minute ripped-from-the-headline-writers' view of the impending war, unhelped by the army of writers working on it throughout production. But also very much helped by the visual effects and production design.
