A seamless blend of humor and thrills set on a transcontinental train where a young English woman (Margaret Lockwood), having dozed off, awakes to find that the tweedy-whimsical old lady (Dame May Whitty) with whom she had been conversing has disappeared. The Lady Vanishes is squarely 1938, as the train speeds through the Tyrolean Alps to a place where nobody can be neutral. A Launder-Gilliat script and the first appearance of that delightful duo of twits, Naunton Wayne and Basil Radford, assure that, although war and Hollywood were in the wings, there might at the very least always be an England.
