The movie replaced Haradrim soldiers to show Easterlings Frodo & C/O hide from at the Black Gate (even if Easterlings indeed were seen in the distance in the chapter), and took [big liberties with] haradrims apperence to create a Rhûn look;
It's proper that the mvies contain Easterlings since they are depicted in the books, but what we have is limited and not suggesting what we at end got got:To bad, would liked to see those axemen or war chariots [who I picture to been inspired by Assyrian, Babylonian and Egyptian examples]
No actually it isn't
TATW could had used the movie look without inventing the whole Loke-rim background story; but it's in their artistic freedom to chose a made up reason for the aesthetics non the less.
@ Despondent Mind
It's an easy impression, but if one dig into it Tolkien is far more complicated in his legendarium than to go with simple racism, and he considered racism a folly himself:
In the First Age Morogth had put his effort into corrupting Men, but it's not an easy matter of "hites are good and coloured got corrupted".
The people of Bëor, one of the Edain houses who joined the Elves in the wars against Morgoth, were mingled with Easterlings, and the Easterlings who came were only to a part aligned to Morgoth:
Many who did help Morgoth to victories did not do so out of evil of heart, but trough lies and terror which is the constant tools by which Men are made to not oppose:
And the people of Bór were faithful to the Elves and fought till their end against the allies of Morgoth.
In the Second Age
but its trough the manipulations of Sauron, in areas where the Elves and Dúnedain have not spread the 'evangelium' of Erú and the Valar, by indoctrination and not related to race, just as the kinfolk of Haladin (another of the Edain, forefathers to the Dúnedain) in the west were influenced by and sometimes worshipped Sauron before the Dúnedian returned - and still it should be underlined that
most, not
all, in the East and South turned to evil.
Again it's much trough terror and fear as tool:
(and yet he, at his greatest point of power, was not lord of all, as seen)
And so it goes on, where the actually most evil and wicked among Men are not the Easterlings or Southrons but the Numenoreans/Duendain, who long before Sauron made them completly fallen made war upon the Men of Middle-earth to make them slaves and plunder their lands for their own gain, and at end committed human sacrafices etc.
Gondor may represent good but they were also imperalists who expanded for their own power and glory, and faced civil war when racist among them under Castamir opposed marriages to other races; racists who commited treason, terror and dictatorship - while it proved that mingling with other folks did not reduce the southern Dúnedains features, which the Castamirians feared.
It should at this time be stressed that the Numenoreans/Dunedain is a race apart not based on evolution, but because God gave features to them as had not been granted other mortals, and the losses of such features were unavoiadble in Middle-earth by default but increased by acting evil, a.k.a in opposition to Erú's will.
We shall further not forget that those Easterlings and Haradrim who came to the west and thus enter the stories that are intended to represent remaining chronicles written by peoples in the West, were those who were in the service of Sauron, willingly or forced, while we do not meet the others; it was not the nice chaps who came west.
In the end of the Third Age:
If Tolkien was a racist by simply talking about races, fine, then he is, yet if what is meant is to value persons based on biological race and belive that some races are better than others, then he is not [Orcs is a side matter, as its a theological issue]. And the lack of moral superiority and value as a human being given to someone because of their mortal shell (even Elves, who is a race of the same species as Man, fall to evil) is what I care about.
Personally what concern Easterlings I just as much percive Tolkien had vikings in mind as mongol people etc., because the only described easterlings in LotR had large beards and big axes, while the only named easterling people are the Variags, which is another name for the varangian guard in Constantinople, that were Norsemen (while later often anglo-saxons). And it make sense, because prior to an European JRR was an Englishman, and from a British perspective the vikings (especially Danes) came from the east
