“The Lady Vanishes” (1938); dialogue by Sidney Gilliat, unassisted this time by J.B. Priestly, as he was on “Jamaica Inn.” This one has way too many twists and turns to elaborate. Miss Froy is an intelligence agent carrying a coded message in a song. She, Iris, and Gilbert are all on a train heading out of Bandrika, a mythical East European country. Nearly everyone else on the train is a bad guy, bent on eliminating Miss Froy before she can reach the Foreign Office in London with a McGuffin message. She vanishes, and Iris can’t get anyone to believe she was on the train—except Gilbert. They find her, she entrusts the tune to Gilbert, and she escapes, suddenly running vigorously through the woods while the train is under siege—after having been portrayed to this point as frail—although she may have been shot during her escape. Iris and Gilbert make it to the FO, but Gilbert has forgotten the tune. They enter the building and hear the tune being played on the piano—by Miss Froy. In addition to the train motif, that of birds is present as Iris is “attacked” by a magician’s pigeons, a magician among whose repertoire of tricks is the “vanishing lady”; and brandy figures prominently, as in some other Hitchcock films.
