[Tuor of Gondolin]

That picture of Sauron does seem to be Annatarish. I imagine they
considered it as a conterpoise to Galadriel when tempted by the
Ring. it would have violated book canon, but that didn't stop PJ in
other ways, such as Gandalf beating up Denethor.

I prefer Tolkien's concept of Sauron, expressed in Letters, as someone of
large size, but not gigantic, to the "swiping twenty at one blow" Sauron
in the movie prologue, although the prologue, both movie and extended
dvd, was otherwise brilliantly done.
