Likeable urbane comedy about an ill-fated courtship and the romance that springs up in the shadows behind it. Grant and Hepburn are fresh and fun to watch; Grant impresses with what feels like ad-libbed quips and shows off his vaudeville background by doing numerous gymnastic stunts. Hepburn sheds her usual stuffy airs and lets fly as a "black sheep" heiress, the betrothed's sister. Cukor directed it in his best imitation of Howard Hawks, but with his own personal style added -- like the "realistic" feminine relationship between Hepburn and her sister (Nolan) which deteriorates by the film's end into stereotypes.
