American comedy written and directed by Billy Wilder. C.R. MacNamara (James Cagney), an ambitious Berlin-based executive for an American cola company, sees his chances for advancement go up in smoke when his boss' daughter (Pamela Tiffin) comes on holiday to Berlin and ends up marrying a fierce young communist (Horst Buchholz). With the boss due to visit in a few days time, MacNamara sets to work, juggling angry Russians, officious Germans, and his own increasingly-exasperated wife, as he tries to put matters right.
