The Dunedain?

[Tuor of Gondolin]

I'm trying to recall if there is any mention of other rangers in the movies.
I would think a nonbook movie viewer would think he was "The Last of the
Dunedain" to paraphrase an old movie. Presumably PJ cut them out to
"simplify" things, but, since he had to have elvsees at Helm's Deep I can see
no compelling reason for not including Halbarad, his band, and Arwen's banner.
Parenthetically, one of PJ's errors at The Pelennor Fields was to not show the
banner unfolded on the lead ship and Eomer's reaction. Another was to not
have the charge begin in the dark and then have morning come.

(Theoden's) golden shield was uncovered, and lo! it shone like an image of the Sun, and the grass flamed into green about the white feet of his steed. For morning came, morning and a wind from the sea, and darkness was removed, and the hosts of Mordor wailed, and terror took them, and they fled, and died, and the hooves of wrath rode over them. And then all the host of Rohan burst into song, and they sang as they slew, for the joy of battle was on them, and the sound of their singing that was fair and terrible came even to the city.

And as for the Army of the Green Slime attacking at the Pelennor Fields!

However, PJ did elements of the movies quite well. On balance I thought his
best effort was FOTR.
