This movie plays more like something Hitchcock would have directed in the thirties. It also have the misfortune of being released while he was in his prime, so it comes off archaic for the master. I rather enjoyed it though. I thought Jane Wyman had considerable charm and innocence to play her character and make us care for her. Marlene Dietrich plays her part well, and Alastair Sim gives nice comic relief as the father to Wyman's character.
Its true that the movie cheats and gives us a surprise ending that really doesn't play with what we're given. This is a flaw and will forever keep this movie from being a masterpiece. However, it is lite viewing, and it has some excellent and charming scenes. The scene of Eve and the Inspector in the back of the taxi was rather nice, at least I thought so. Plus it has more humor than some of his other works. It certainly isn't rear window, but its worth watching for Wyman's fun and interesting performance. Its nice to see a heroine more so than a hero in something of Hitchcock's. Plus you can find out a hazard of the safety curtain that we hadn't thought of. 8 out of 10.
