There are historically accurate war movies...generally made much closer to ww2...
Then there are popcorn war movies, in which the Americans fought everywhere and almost all looked like John Wayne....
Then there's modern popcorn war movies, which are not about the world wars usually anyway...Vietnam, Iraq....occasionally George Clooney will turn up....
The only thing most of these have in common is the 'movie' part, and reminding us how disposable a male lower class population can sometimes be, and how women are terribly good at being nurses or worrying about the menfolk. Oh...and how wanting to go home and marry your girl and have a farm is actually more fatal than smoking.
In terms of the wars getting women into work...well, it's a bit like suffragettes in film. What they mean is 'well heeled white women' as the poor folk of any colour were already working, and didn't get the vote until much later. (In the UK anyway...not even all men had the vote in most of the popular fiction time periods...there's about ten years between universal suffrage for men and universal suffrage for women in the UK.)
I would like to see some more honest accurate films, but only popcorn flicks or political flicks win awards and audiences. I want to see Red Tails, but I don't go in much for war films in general so haven't got round to it yet. TBH I barely have time for any films xD
I did watch hotel Sahara the other day mind you. Terribly amusing.
