This movie is not bad at all,not one of Lemmon's best by any stretch of the imagination but it has some funny situations and its likable for the most part.Near the ending it gets completely out of hand and instead of comedy-mystery which is the most part,it becomes mad slapstick for no apparent reason.Is like someone told the scriptwriter that a Lemmon movie should be crazier than what they had up to that point.Anyway,its kinda weird this way from that point on but you get to smile and the stars are all likable.Novak is at her sexiest, even in B&W!!Funny role for Astaire who was at his second career by that time,plays a manipulating official at the American Embassy in London with an eye for Novak.
