As he conducts a symphony in a crowded concert hall, an esteemed musician imagines different ways to deal with his wife's reported infidelity in this Preston Sturges comedy. Rex Harrison is perfectly posh, snobby and indignant in the lead role, though his character is more than a little hard to relate to as he simply assumes that his wife has been unfaithful based on hearsay without ever confronting her and without any real evidence. In this regard, the film plays out a lot like 'Othello', though with a pronounced black comedy streak as some of Harrison's imagined solutions to the issue are really rather grisly. In arguable bad taste or not, 'Unfaithfully Yours' is laugh-out-loud funny at its best with the zaniest moments coming from Harrison later trying to act on his imagined scenarios, only to find himself foiled by unreliable technology and other things that get in the way. The film is incredibly slow to build up though, with over 45 minutes elapsing before Harrison starts to concoct revenge scenarios. While this build-up does allow us to get under his skin a bit better, it also makes him seem all the more foolish for not doing anything more to confirm the suspected infidelity. A rather nice touch of the movie is how his anger gives him the fuel to conduct more brilliantly than ever, but this is not a first rate Sturges comedy, even if it certainly never once bores.
