Poor guy obviously hasn't read the book. In what JRR actually wrote, the climactic battle of the Pellenor Fields was between the Haradrim and Rohirrim. The Haradrim were southerners, who varied from middle-eastern looking to negroid. JRR even makes one crack, if I remember correctly, about the latter looking almost like goblins.
PJ chickened out on this one.
FWIW, I did find it creepy that almost every character in the film had blue eyes.
What **I** found spooky was how many of the characters had cleft chins!
Count 'em. Miranda Otto, Wood, VMort, Sean Bean---more, I think.
A cleft chin, dimpled chin, is rather rare in population. I believe I read once that it is a benign manefestation of a cleft palate.
As for blue eyes, almost everyone in Tolkien had *grey* eyes--? Except for hobbits, styled after "brownines"--generally had brown eyes and hair.
