This is how the Polish were indoctrinated into the UK as a minority, which might sound strange to modern America but back before everyone had an iPhone, your national identity is how you were registered as a minority.
It was an epic military blunder....for the Germans who HAD the Allies by the balls but didn't press far enough. Blame herr Fürer for that one.
I really LOVED this movie. It's a meditation on what defines bravery and what defines cowardice. Where does self-perservation fall in the equation?
There's very little dialogue. Very little action. People die in the most unfortunate of ways.
Really it's not about the enemy but when you have half a million desperate individuals from the UK, Europe, etc.
The hardest part to digest is the most heroic person ends up paying the biggest price.
Spoiler:
Most war films are about the battles but this is kind of a little British nationalism and what YOU the Civilian can do for YOUR country.
and I liked it.
