I know we're diverging from Real Life here, but to a purpose...
If you have Netflix, dig up "Five Came Back." It's the story, as told by Spielberg and Ub Iwerk's* grand-daughter, about the Five that went to WWII and film it.. Capra, Ford, Huston, Wyler, Stevens.
They all saw things, IRL, and filmed them. Some were shown at Nurenberg, and served to tighten the noose about a few necks just a bit tighter.
Some of those wartime films they made for propaganda are a very tough watch today. Seen Wyler's "Memphis Belle?" How about Ford's "Midway?"
How about "Let There Be Light?" I was tore up in that one. Not all wounds are caused by bullet, shell or blade. Not all wounds can be seen, or stitched up. A lot of my friends in PR had Korean and Vietnam vets for dads - enlisted, mainly Army. I went into the military eyes wide open, after hearing their tales for 10 years. Well, barely any tales. They didn't talk much. When they did... they were different people. And this film just made me T.T when I saw it. The didn't know what to call it when they made it, today we call it PTSD.
They all came back, and all made movies again. Capra made "It's A Wonderful Life." Wyler made "The Best Years of our Lives."
One, to me, stands out very brightly against the rest, so much so I bought it: Ford's "They Were Expendable"
Not every Hollywood war flick made is hokum. Some were heart-attack serious, and this was one of them. Ford cast a real PT boat skipper. The poor guy took 4 days to get ready to film, and Ford let him have the time. The actor was PTSDing real hard. You thought the submariners had it rough and had to pretty much forage/steal their supplies? PT boats were worse. No one cared about 'em, apparently, or the men who drove them. The title was dropped in the film as referring to the boats, but the context is that the men were just as expendable.
This one even had John Wayne in it. To hear Spielberg say it, they were trying to get this one scene done, and Wayne kept messing up the salute. Ford goes "G*damn it John, can't you salute like someone who's served?" At which point Wayne walked off the stage, and Ford broke down sobbing. In broad daylight, in full view of cast and crew. These two men were long-time friends, and this still happened.
Remember that, when you watch these immediately post-war movies.
I was raised by a pack of WWII vets and their crazy sisters. Not many stories. One of them was in Italy and saw Benito swing, I'm told. They didn't talk much about it. They didn't talk much about anything war-related, other than the machinery. The guy that saw Benito swing had a M1905 bayonet that looked longer than my arm.
And despite all that, I still signed up.
People have no idea what freedom cost.
