Precise and without pretensions, ["The Lady Vanishes"] is the best spy thriller in a long time: growing suspense from beginning to end, no empty threats, no sticky romantics, no stupid explanation, no misleading clues—every minute is used to advance the plot, which has an almost mathematical logic. Of course, a whole arsenal of old tricks is employed, but with authority and irony. By this quantity is changed into quality. About the excellent use of the comic relief provided by two English sport enthusiasts one could write an essay. Besides being an excellent story, presented with technical perfection, the picture vividly conveys the ruthless, machine-like methods of an organization which has the features of a modern totalitarian system. Our compliments to Mr. Hitchcock: the thriller addict leaves this film not only highly satisfied but with no pricks of conscience at having been taken in again by trash.
