It’s anyone’s guess as to what compels Disney executives to keep churning out low-effort live-action remakes of beloved animated movies they already did decades ago.
I’m guessing extending copyright somehow? If the plot of a new but ho-hum film exactly mirrors an earlier classic film that folks might actually want to use when it enters the public domain, I imagine ho-hum can provide cover for the classic?
That’s not how copyright works. For example the recent live action Winnie-the-Pooh movie had no impact on the character itself coming into the public domain.
I still haven’t watched any of the live-action remakes of Disney’s animated classics but I might be persuaded to watch a Snow White remake about a goth girl who runs away to lay low with seven misfits living in a communal punk house.
I suspect these casting decisions have little to do with US culture wars and a lot more to do with the simple fact that the blockbuster movie industry is thoroughly international now and the world has a lot more movie watchers with brown skin than with skin white as snow.
Focusing less exclusively on stories about white people is only part of a “culture war” in the sense that angry bigots want to pick a fight about it.
Most audiences are happy to enjoy films starring people who don’t look like them, as long as there are a reasonable number of other films starring people who do.
