In the early part of the movie Flint knocks out those two fake guards. He tells Cramden they were fake because they were wearing Battle of the Bulge ribbons. When Cramden states there is no such ribbon, Flint says "exactly." If there was no such ribbon why did Flint call them Battle of the Bulge ribbons since he obviously wouldn't have known what they looked like?
Yeah, I really liked the movie, too, and I'll always have a special reason for remembering it: I first saw it the night before I got out of the service.
Flint makes a reference to buttered Saffron in the bouillabaisse and only 1 place in Marseilles do they use the particular proportions, what if they had been health conscious and used margarine instead of butter?
"All opinions are well reasoned and thought out, any similarity to reality is pure coincidence."
There are "offical" medals, issued by the government... and then there are commemorative medals, which are unofficial medals that anyone can make. A serviceman can only wear ribbons that correspond to "official" medals, not commemorative ones.
There is a commemorative medal for the Battle of the Bulge. It's even plausible Flint has one of those himself since it is revealed early in the movie that he was awarded a Croix de Guerre.... that is to say he most likely saw action in France during WWII... where the Battle of the Bulge took place.
So when Flint sees the impostors wearing ribbons for a non-official medal... that is to say a medal for which "there is no ribbon"... *BAM*.... down they go.
I didn't even know this myself until I saw the movie again just recently, and mind you this movie has been a favorite of mine for nearly 30 years! But for fun I Googled "Battle of the Bulge ribbon".
