I'm linking the article but the actual dunk is on redditors who see this and cheer, completely ignoring that this is an extension of how much power/influence the American military has over hollywood film. Want to film anything that might have the military in it? You gotta play ball babyyyy! Ever notice how weirdly patriotic and jingoistic almost every film that features a tank is? They played ball babbyyyy!!!
there was a good comment on reddit at least though https://old.reddit.com/r/entertainment/comments/14o3xt8/defense_department_declares_it_wont_work_with/jqbfo50/
They don't exactly work with a lot of films to begin with. If they do, they have a stipulation that the movie needs to depict military service in a positive light. They won't help you make an anti-war movie. Which while I guess is fair from their perspective, they are stating this like it is a game changer.
The funniest outcome of this is movie studios looking at this declaration and just saying "I guess we are not using defense dept assets, because we want China's money."
