I have a bunch of requests from Fellowship of the Ring - sorry there are so many, and please don't feel obligated to do too many of them, or any at all!
Galadriel in the prologue:
"But the hearts of men are easily corrupted. And the Ring of power has a will of its own."
From Bilbo's birthday party:
Merry: You're supposed to stick it in the ground.
Pippin: It is in the ground!
Merry: Outside...
Pippin: It was your idea!
On the way to Rivendell (I realize this one's rather long, so maybe only sections of it, or the whole thing broken up into smaller files):
Aragorn: Gentlemen. We do not stop 'till nightfall.
Pippin: What about breakfast?
Aragorn: You've already had it.
Pippin: We've had one, yes. What about second breakfast?
Merry: Don't think he knows about second breakfast, Pip.
Pippin: What about elevenses? Luncheon? Afternoon tea?
Dinner? Supper? He knows about them, doesn't he?
Merry: I wouldn't count on it.
A particularly adorable orc in Saruman's tower:
"What orders from Mordor, my lord?"
Elrond in Rivendell:
"Men? Men are weak."
At the council meeting:
Legolas: This is no mere Ranger. He is Aragorn, son of Arathorn. You owe him your allegiance.
Boromir: Aragorn? This is Isildur's heir?
Legolas: And heir to the throne of Gondor.
Aragorn: Havo dad, Legolas
Boromir: Gondor has no king. Gondor needs no king.
(I think you might already have some of that, but I was wondering if it would be possible to get the rest of the conversation, especially "havo dad, Legolas"

Elrond at the council meeting:
"The Ring was made in the fires of Mount Doom. Only there can it be unmade. It must be taken deep into Mordor, and cast back into the fiery chasm from whence it came." (or just the last sentence)
Aragorn, after Boromir tries to take the ring:
"I would have gone with you to the end. Into the very fires of Mordor."
Sorry again for all the requests, and thanks for doing such a wonderful job with this website!
