(Liv Tyler's character Arwen comes not from the story but a footnote, obviously a ravishing one.)

Not entirely accurate, she was in the books. It was the extended romance bits that were based on the appendices.

I think Jackson's Arwen takes much from Luthien in the Silmarillion, in addition to the Appendices--a very smart thing to do, as the romances are similar and ancestors of both Arwen and Aragorn.
