It had been a long time since I had seen it, and it was just as good as I remembered. The four leads (Cary Grant, Grace Kelly, John Williams, and Jessie Royce Landis) are all perfect. The scenery is spectacular and the script is really funny. The "making-of documentary" on the disc is pretty nice too.
I don't understand why this one isn't considered a classic like Rear Window or Vertigo or North By Northwest except that it is not nearly as serious a movie. Cary Grant is rarely in danger. I guess that the only real shortcoming compared to those is that the villain is not exactly formidable, and is not even revealed until the end.
The denounment, where Grant is spotlighted on the roof and everyone really thinks that he is the thief, really reminded me of the ending of Frenzy (1972). In that one, Richard Blaney (Jon Finch) has escaped from prison to hunt-down the necktie strangler who has framed him, and ends up walking into the bedroom of the strangler's latest victim. To make things worse, the police detective catches him there and his goose looks really cooked! Of course, Hitchcock really knew how to build up suspense until the very last shots of his films...
