Can anyone think of another instance where the exalted filmmakers completely subverted Tolkien's original intent?
Plenty of other examples.
Don't have time to detail them though.
I know the speech is inspirational to some, but that doesn't really fit Middle-earth of the long defeat.
Sam's reflection that the menace of Sauron threatening to engulf the world is 'only a passing Shadow' is directly from the book.
(One of LotR's most beautiful passages too.)
Did Movie Aragorn say that, then, in his Black Gates speech? (I honestly can't remember.)
I don't think he was wrong.
, in the long perspective of history (and Eru), only a passing Shadow ... seems a Tolkienian concept to me.
