Billy Wilder's "One, Two, Three" starring the great Jimmy Cagney! Correctly depicted life in occupied Berlin.
One,Two,Three is on my Alltime Worst Ever List. Stunningly unfunny. Don't watch it if you don't want to get a headache from NOT laughing.
Billy Wilder is one of the least dependable of classic era directors, capable of making classics and total junk.
