Dialogue as bright as the colour, misunderstanding piled on misunderstanding and production values as high as the unlikelihood of the story: battle-of-the-sexes comedies never came glossier than in the Doris Day-Rock Hudson sparring matches in the late Fifties and early Sixties and this is one of the best. Advertising exec Rock has to invent a non-existent product to cover up his chicanery and rival Doris goes after it without realising that it doesn't exist. Smoothly, confidently made by Delbert Mann, the film has delightful supporting performances from Tony Randall, giving his usual impression of a demented flywheel, Edie Adams, delicious as a brainless chorus-girl, and Jack Kruschen as a bumbling inventor called in to give substance to the mythical product. Sheer enjoyment, sophisticated in technique and execution, and marred only by the insertion of a soupy song from Doris at quite the wrong moment.
