Cary Grant has an odd passion in the comedies for remarrying his first wife and leaving a new boyfriend (here, as elsewhere, Ralph Bellamy) bemused and bereft. Irene Dunne is the once and future wife. ("No one conveys a certain mystery at the heart of (the screwball) heroine as strongly as she does...the combination of common sense and uncommon passion..." --James Harvey, Romantic Comedy). A dog named Mr. Smith is the McGuffin but the real issue here is Truth in Marriage: the less ideal it is, the more ideal it is. (Or, as Kay Francis puts it in Trouble in Paradise, "Marriage is a beautiful mistake two people make together.") Bellamy enters whistling "Home on the Range," and we know that it is the death-knell to desire. Better the mutual magnetism of antagonists, played out in the fast-talking style of Leo McCarey's improvisational technique. McCarey's arrows are slung in all directions: Dunne horrifies high society with a tacky song about the American Dream, while Grant withers even the most ardent cowboy with a line: "Pardon me, you're sitting on my prospectus."
