Loved the movie, but for one thing (heavy spoilers)
Warning, heavy spoilers ahead.
I really enjoyed this film. I wasn't sure where it was going to go. I deliberately avoided reading anything about it. I only knew that a woman assumed the identity of another. I thought it was going to be a drama and happily for me, it turned into a suspense, my one true love. I love suspense! I've seen most and had forgotten that this one often shows up on lists. I had yet to see this one so it was a thrill for me.
The thing that bothers me is the whole shed incident. It was never fully explained. Yes, I understand that we're probably to assume that Alan tried to kill Chris via his chemistry set. Was this supposed to be the beginning of the rift between Margaret and Alan? If so, we'll never really know, will we?
Also, I have to wonder why Alan saved Victoria/Karin from falling through the shed floor. It would have solved one of his problems and would have been truly accidental, or at least it may have started that way. Unless he felt that authorities would want to know how the hole came to be in the first place. That would be a problem, wouldn't it?
I don't know. It just felt like a chunk of the film was missing. Then, did Victoria go on as Karin or no? I like neat endings, but not all give us that.
In any case, if you like this film then I have two Hitchcock films to suggest. The first is Suspicion (1941) with the recently passed Joan Fontaine and the second is Notorious (1946) with Ingrid Bergman; both star Cary Grant. These are similar in nature. Incidentally Notorious is also post WWII whereas the former was released only weeks before Pearl Harbor. I highly recommend them, if you enjoyed how this one played out. In fact, I think I'm going to go and watch them right now!
