Much of the problem with "24 Hours" might be because of when it was made. Many of the films from 1929-31 are a bit stilted and slow compared to ones made just a few years later. And, stilted and slow is definitely the way I'd sum up this film. This is really weird, however, as the film is filled with murders (one is particularly vivid and brutal), adultery and more....but the characters seem unperturbed and behave pretty much like like they are bored or talking about stamp collecting. This is definitely true of the leads, Kay Francis and Clive Brook...a couple who are cheating on each other yet there is no energy at all when they admit this to each other. There are some sparks from Regis Toomey and Miriam Hopkins...but not enough to recommend this rather boring film. And how they could make this plot boring is beyond me! The film could have definitely used an infusion of energy and zip!!
