Hitchcock at his sharpest. Art and commerce in a delicious salad with all the right ingredients. A brisk screenplay by Ernest Lehman a Cary Grant that is just pure delight, Eva Marie Saint fresh out of her Oscar from "On the Waterfront" is an icy blonde with a brain. James Mason, the ultimate foreign sinister not to mention Jessie Royce Landis and Hitchcock brings Bernard Herrmann to wrap it all up in one of the most infectious scores imaginable. A real treat.
