The Lady Vanishes (1938)

Part of the summer series Alfred Hitchcock Presents!

On a train headed for England a group of travelers is delayed by an avalanche. Holed up in a hotel in a fictional European country, young Iris (Margaret Lockwood) befriends elderly Miss Froy (Dame May Whitty). When the train resumes, Iris suffers a bout of unconsciousness and wakes to find the old woman has disappeared. The other passengers ominously deny Miss Froy ever existed, so Iris begins to investigate with another traveler (Michael Redgrave) and, as the pair sleuth, romantic sparks fly.

This British Hitchcock picture is one of the master’s best.

Austin Chronicle

This is vintage Hitchcock, with the pacing and superb editing that marked not only his 30s style but eventually every film that had any aspirations whatever to achieving suspense and rhythm.
