I read about this long before I saw it. Francois Truffaut’s comments in the Observer magazine one Sunday tickled my kiddish fancy but even in the 1980s Hitchcock screenings were a hard find on TV particularly of this vintage. The fact that it’s Hitchcock is rather moot (or controversial!) from an authorship perspective: it wasn’t written with him in mind at all (it was intended for Roy William Neill) and yet the tropes became part of his evolving cinematic signature. It was adapted from Ethel Lina White’s novel The Wheel Spins by Frank Launder and Sidney Gilliatt, a formidable pair who would become one of the more fascinating partnerships in British cinema. On the train trip back to England from her pre-marital ski holiday with her girl squad, socialite Iris (Margaret Lockwood) befriends an old lady governess Miss Froy (May Whitty) but when the woman disappears nobody believes her until she finds an ally in musicologist Gilbert (Michael Redgrave) whose kick-dancing kept her from going to sleep in the hotel. Every time Iris finds proof of the old lady’s existence it simply (and literally!) evaporates. Is she going mad? Everyone else seems to think so. The cast on the train are a rum sort: Charters and Caldicott (Basil Radford and Naunton Wayne), the cricket-obsessed Brits (who would appear in a handful more movies as these characters!); the adulterous couple the Todhunters (Cecil Parker and Linden Travers); a weird baroness (Mary Clare); a doctor (Paul Lukas); and a nun (Catherine Lacey): all of whom seem intent on keeping Iris quiet from her apparently paranoid observations for various reasons of their own. Some turn out to be more political than others … This eve of WW2 comedy thriller persuaded David O. Selznick to invite Hitchcock to try his hand in Hollywood: after three relative box office failures, this was a surefire hit. The effects are good (miniatures), the suspense never lets up and there is a rare menacing tension which the political subtext amplifies as quickly as the train steams ahead to the various troubled border controls. Quick-witted, smart storytelling with a winning cast: who could wish for anything more? What did Truffaut say about this? He said he saw it once a week at a cinema in Paris and every time he tried to figure out how it worked he forgot because he got so caught up with the story. Oh yes. That’s it!
