Clearly the casting director made a serious mistake.
This movie would have been so much better if Denzel Washington played the senior Navy guy on the jetty and Charlize Theron flew the Spitfire instead of Tom Hardy. To cater for the French and older generation could have cast Catherine Deneuve as the French soldier.
More women and people of colour would have gone to see it.
Nah ! Just kidding guys.
However just think of the possibilities for "PC" movies. Mrs Custer's Last Stand, Daphne Crockett and Davinia Bowie heroes of The Alamo, the 300 Spartan Wives and to be fair 4,000 nasty British red coats attack a Company of Zulus at Rorkes Drift. However this poses some problems as do we allow the Indians to win over Mrs Custer or the Mexicans over the female defenders of the Alamo ? Wouid need to consider all the angles and perhaps make them honourable "draws" so as not to offend anybody.
