I believe Harry Knowles from AICN has read the whole script and I believe I read a quote of his (or was it Moriarty) that said "the scouring is in but it's very short." I just looked for a half an hour trying to find it again but can't.
Anyway, couple this with the reports of a
Frodo voiceover after the wedding and I think it'll go something like this:
Wedding...montage epilogue with voiceover showing the more important
events of returning home...detached montage of the scouring (something like "then they returned home and to their horror found..whatever...but they were changed
hobbits and with little trouble...whatever, whatever..." -- again, showing scenes in montage form)...then
Sam gets married and they all settle in
Bag End (still montage of course)...Elanor is born (graphic shots of the delivery of course
)...all the while we see shots of Frodo looking unhappy or in pain...then the montage stops and
the Grey Havens scene ends the movie...OR we see Sam return home after the Grey Havens and deliver the "Well, I'm back" line (which would explain the pictures we've seen of Sam with Elanor running to him).
That's my prediction (or at least compromised hope). This gives us the all-important scouring scene and the significance of it without the episodic anti-climax of doing it like the book (which is awesome in the book - don't get me wrong, it just really wouldn't seem right in a movie). Including the killing of
Saruman in this adaption of the scouring scene would be too much (to many specific events to make it work in the montage style) but luckily he's long dead on the spikey wheel (of course we lose the depiction of how low Saruman has sunk but hey, you gotta lose some stuff). If the ending turns out like this, I think I'll be able to live with it. If the scouring is totally lifted, I'll be very disappointed.
