Continuity mistake: Right at the beginning of the movie, the Sergeant pulls his jeep over and headbutts a prisoner who is carrying a Danish flag, seizing it. In the following shot he has his arms open and shoves away another prisoner, no flag in his hands. Next shot, he's standing by the bleeding prisoner, folded flag in hand. (00:02:25)
Factual error: The bunkers which are visible in the movie have not been prepped to look how they should in the years after the war. They would have been plastered and painted, not looking old and rusty as they appear in the movie.
