      Let's say that the first version was the work of a talented amateur and the second was made by a professional," said Alfred Hitchcock, comparing the two filmings of The Man Who Knew Too Much. Where the first had an easy wit and a kind of grimy nonchalance, the second is everywhere a richer film -- not only in its technical execution, but also in the complexity of its characters and themes, and, most of all, in the depth and directness of its emotion. The fourth and final collaboration with the gifted screenwriter John Michael Hayes, this is one of Hitchcock's masterworks, impeccably photographed by Robert Burks, with a brilliant Herrmann score and flawless performances from principals and supporting players.
      The plot outline is much the same as the original, although the kidnapped child is now a boy, and the original characters of Abbott and his nurse have become the far more complex Mr. and Mrs. Drayton. The story now opens on a bus, with a closeup of a young Hank McKenna seated between his parents, Dr. Ben McKenna and Jo Conway McKenna, and internationally famous singer who has abandoned her Broadway career in favor of her husband, whose medical practice is in Indianapolis. The opening image synthesizes a contradiction, for Hank is a link between the parents; his absence will threaten their stability by dividing them and yet enables them to rediscover their interdependence as they struggle to recover him. In fact the central issue in this picture is neither the political situation at the core of Louis Bernard's murder and the child's kidnapping (that crisis, whomever it involves and whatever is at stake, comprises Hitchcock's MacGuffin). No, the problem most explored here is the relationship between Ben and Jo, the delicate state of her emotional health, and how a man who thinks he knows so much (Ben) must learn the contours of his own interdependence with others.
