An over-long and only spasmodically amusing romantic comedy, clearly made as a tribute to Lubitsch. Set in Paris, it concerns the predictably blooming love between wealthy American playboy Cooper and Hepburn, the innocent but determined daughter of Chevalier's private detective, whose cuckold client (John McGiver) intends to take revenge on Cooper with a pistol. The script - Wilder's first with IAL Diamond - has its moments, but by and large it's conspicuously lacking in insight or originality, while Hepburn's fresh-faced infatuation for her all too visibly ageing guide to the adult, sensual world comes across as faintly implausible.
