I just saw this: https://www.google.com/amp/s/amp.dailydot.com/parsec/lotr-amazon-elves-of-color-twitter-hoax/ It got me wondering about possibilities. Introducing "Elves of Color", to use the article's term, would seem to be a stretch, although I suppose a rationale could be a group of "Southern Elves" unmentioned by Tolkien. That would be a major divergence from the books (although as PJ has demonstrated, that's no problem for filmmakers!). There's another possible track, though: we know that the young Aragorn journeyed to Umbar, and both Near and Far Harad, presumably as a spy in the latter two places. It's also conceivable that he might have tried to stir up resistance against Sauron and the Black Numenoreans. I can imagine a story-arc which finds him meeting and befriending one or more of the Haradrim; after all, it would get pretty boring to have a TV series where the hero was constantly alone -- no dialogue! And you can't make all his interactions fight scenes; he would need a companion from time to time -- for exposition, if nothing else (this is assuming the series is about "Young Aragorn" -- Amazon is still tight-lipped about it). Anyway, that's my idea -- what do you think?
