This is the best Hitchcock and one of the best movies I have ever seen. It was perfect. In fact, it had only one flaw, and that no doubt was the government's doing, not Hitchcock's. A Porter tune and I think a signature tune of Dietrich's and sung by her in this flick ("The Laziest Gal In Town") goes "It's not cause I wouldn't. It's not cause I shouldn't. And lord knows it's not cause I couldn't. It's simply because I'm the laziest gal in town." Well, the censors had their way and changed the line to "And you know I couldn't." Bleah! But that is the only thing wrong with this wonderful, suspenseful, surprise and twist filled, humorous (and I mean genuinely funny!) movie. The acting was perfect. The directing was perfect. And the whole thing was fascinating and great! I loved it.
