I mean, it's depressing but not surprising that Andy Serkis would use racist language in his defense of LotR. Māori actors being present in Peter Jackson's LotR films doesn't change the fact that they were cast almost exclusively as the villains. This did not go unnoticed by (some) critics even at that time. For the Haradrim, the Weta crew *were*, thankfully, talked out of using exclusively African influences, but they then went with designs based on Kiribati armor, with the excuse that the island was "so small" that the people couldn't possibly be insulted at the appropriation of their culture. Can and should filmmakers do better now? Absolutely, but it's clear that toxic nostalgia for the original film trilogy is driving a lot of these racist choices.
I didn't want to get into this on my main post/s because every time I tried, I ended up on a tangent that derailed the point of my slamming Andy Serkis.
-Okay, I did touch a little on the first bit without explicitly saying it, but the other points I did not.
(I really don't think "they were cast almost exclusively as the villains" needs to be expanded upon or debated. It is a terrible, deeply racist look under the modern lens. There is no nuance to explore. We are better than that. Plain and simple.)
As for the Haradrim/Southron's, I want to add that not only did they switch to Kiribati influence, but they also used the Aztec Empire for inspiration. Which I cannot stress enough, IS NOT BETTER PHILIPPA BOYENS.
Additionally, does anyone else remember the production team wearing dark makeup and dreads for a cameo as the crew of the Corsair Fleet? Just me?
There is an extended segment in the Appendices about this cameo where they laugh about how much brozer and dark makeup they had to put on them.
I will push back on the last part of what you wrote. This problem is rooted in the way Tolkien wrote about the Harad and the People of Rhûn (and even Orcs and Goblins) and how it creates difficult situations for people adapting/writing about his works. On one hand, there are parts of Tolkien's text that read deeply racist, on the other his characters are capable of recognizing each other's worth despite cultural divides and he also was about as staunchly anti-white supremacy as a middle class middle aged white man could be at the time.
This does not absolve the production team in the same way it doesn't absolve Tolkien, but it gives context to their ignorance.
We have room to consider this and improve upon the flawed base. The 2000s brought more female representation into the fold. It's time to reckon with the racist and ableist tones. And I truly don't care if we have to actually consider George RR Martin's shit eating quip about Aragorn's tax policy and his treatment of orcs. Tolkien included diversity in his world, accidentally or not, and you can no longer ignore it. We are fully capable of putting good representation into Middle Earth and even as the biggest continuity snob alive I could care less if they blind-casted Aragorn.
Misunderstanding and the global wave of tolerance of fascism and white supremacy is what is driving this decision, and I'm not going to get off Serkis's back until he rescinds the comment.
