The film is one of those romantic comedy prototypes. Which means you can guess the ending pretty early, the exchanges are witty and there is a big breakup somewhere in the middle. But with Coburn thrown into the mix the whole thing became way more unpredictable and for me way more enjoyable.
The demeanor with which Coburn sets up the whole affair between McCrea and Arthur is just amazing. And I have to admit that I loved that little scene with the trousers. Totally silly, but in its harmless way a great deal of fun. There were a couple of other scenes like that, but this one just stuck to my mind.
