An American writer meets the wife of a civil service acquaintance and quickly starts an affair with her. However Maurice is plagued with feelings of guilt and jealousy against Henry having Sarah, and bitterness that Sarah is being deceitful to her husband and perhaps, him too. After a bombing falls near their love nest, Sarah leaves and Maurice assumes that she had wished him dead. When Henry confides in him about his wife's possible infidelity, Maurice poses as her husband and hires a private detective to follow her and find out what she's doing.
I have not seen the remake but was quite interested to see how a 1950's movie would manage to depict the illicit affair between Maurice and Sarah without breaking every moral code of the day. The answer is with lots of talking. The film is significantly shorter than the modern version and had less controversy (or at least, does now) but it still manages to bring things out. The plot is pretty good but relies very heavily on the extended flashback/journal sequence to keep things going. The talk heavy feel is a little tiring but does work well the characters' emotions are brought out well without profanity or nudity.
I don't think Johnson fitted the role that well but he was still good. His inner bitterness and guilt came out well at points and he brings his complex character out well. Kerr is also good although her role is less difficult. She does have to carry the whole journal sequence near the end and she doesn't let the film dip. Cushing only has a few scenes but he is very good. He gives an English gent performance but eventually you can see the cracks as he tries to hold his feelings together.
Overall this is a solid adaptation of the book that manages to bring out the subject matter without the sexual excess of the modern version. While it is a little heavy on dialogue at times, the emotions come out with all the stilted control of the period and it works quite well as a subversive melodrama.
