Cary Grant has an odd passion in screwball 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. (Hers is the “mystery at the heart of (the screwball) heroine...the combination of common sense and uncommon passion”-James Harvey.) 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. Bellamy enters whistling “Home on the Range,” and we know this 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 the line, “Pardon me, you're sitting on my prospectus.”
