speaking of possible filming locations, it's a pretty well-known fact that at least part of why Southern California became the epicenter of the American film industry is because the weather is almost always pretty good there (i say "there" instead of "here" this time since, as i'm typing this, i'm still on vacation in Hawaii

), usually having clear skies and reasonable temperatures which make filming easier in and of itself--it's why the Universal Studios Backlot has seen so much use, including for non-Universal films such as Disney-made
Princess Diaries and
Pirates of the Caribbean. if we want to truly analyze what Confederate media would be like, we should consider what parts of the country have good weather comparable to that (i'm sure most people participating in this thread know that the South in general is pretty humid, which would be a factor against alot of it since outdoor filming could be put on hold by sudden rain) and how that could affect their film industry. Confederate geography would play a big part in this, such as if they managed to get their Arizona territory which could make filming in the desert an option beyond just using it as an on-site location for Westerns.
i agree concerning the point of "we're focusing too much on slavery" here. while that was pretty much the be-all end-all for the Confederacy's existence IOTL, in the extremely unlikely case that they would actually
win the Civil War, i doubt it would become the absolute defining feature of their media. i don't doubt that they'd remain a white supremacist hellhole for the majority of their history through to OTL's present-day (after that, who knows?) but plenty of OTL states were
also extremely racist IOTL but it was more casual--you'll notice that alot of Imperialism Age-media remarks on stuff like non-whites and colonialism in ways that are extremely racist by today's standard, but it's not the heart of the story (for example,
The Sign of the Four, one of the earlier Sherlock Holmes stories, describes an Andaman islander in such a way but it's only incidental to the story, and certainly was just a product of its time rather than Doyle being racist). there might be outdated, minstrel show-style caricatures of black Africans being common and accepted in media for a longer period, but that's probably about it rather than the moral of 99.9% of Confederate media being "the natural place of blacks is working our cotton fields"
