Cheeky little Technicolor comedy in which Laurence Olivier plays a young lawyer who allows a stranded stranger (Merle Oberon) to spend the night in his apartment. She leaves him a card reading 'Goodbye, Madame X'. Then his old friend Lord Mere (Ralph Richardson) contacts him the next day, wishing to sue for divorce because he's convinced his wife spent the night with another man - in that same block of flats. A British farce of mistaken identities
