Well, I've been reading all the posts of this forum, and one that I have found is not here. I was on a Frodo site, and I found some very interesting pictures... they're apparently from the TTTEE feturettes ect, the one on RotK.
They show what could happen if Frodo became like Gollum - which was a possiblity in LotR. I think they could be in the RotKEE, possibly as a dream of Sam's?
If you want to see them:

They're about 12 lines down. There's eight of them (4 of Elijah Wood in make-up, 3 screencaps and one on-set).
What do you think?
