perfectionist hitchcock do not like the opening flaw of this film story and where the initial flashback do not match the rest of the film . but this film be so much more than that once i view it . it might be the only film where hitch do 2 cameo though one be so subtle that it be hard to catch while the other be very obvious . the film do continue most of the theme of his prior work . stairway be a central theme within the plot . camera angle be use with very great care . mostly this be a great performance film . for whatever reason and the cast all have some of their best role act on film . jane wyman and marlene dietrich be both great . while dietrich might have a good performance someplace and this be the best wyman i have ever see anywhere . the male cast be fantastic and every one of them . in this film alstair sim ( who would play scrooge the next year ) have his best performance in any film of his i have see in addition to the classic a wymans father . the support in this film be so strong that by the end and the viewer do not care about the beginning not make complete sense because hitch and the actor have overcome that with a well make movie . hitchcock next warner film would be dial m for murder . while that one be more famous and this movie film in london with a strong british cast be worth while view .
