Please avoid watching this movie which have absolutely no respect for history, is full of anachronisms and is a grotesque apology of anglo-saxon superiority. Learn an read about history. Nolan made a blockbuster probably to please American public. For the rest of the world an especially in France it represents an insult to the thousand of french soldiers who died to allow escape of the English troops. Prefer "week end a zuydcoote" of Henri Verneuil far better.
