FROM THE MOVIES:
"This is no ordinary Ranger. He is Aragorn, son of Arathorn. You owe him your allegiance."
"Have you heard nothing Lord Elrond has said? The Ring must be destroyed."
"And you have my bow."
"There is a fell voice on the air."
"We must move on. We cannot linger."
"A lament for Gandalf"
"I have not the heart to tell you. For me the grief is still to near."
"It is not the eastern shore that worries me. A shadow and a threat has been growing in my mind. Something draws near. I can feel it."
"You mean not to follow them."
"Come on Gimli!"
"They may yet be alive."
"A red sun rises. Blood has been spilled this night."
"You would die before your stroke fell!"
"Hiro hyn hîdh ab 'wanath"
("May they find peace after death.")
"This forest is old. Very old. Full of memories...and anger. The trees are speaking to each other."
"Aragorn, nad no ennas."
("Aragorn, something is out there.")
"The White Wizard approaches."
"That is one of the Mearas, unless my eyes are cheated by some spell."
"You look terrible."
"Your friends are with you Aragorn."
"Shall I describe it to you? Or would you like me to find you a box?"
FROM THE BOOKS:
"Alas! Alas!" cried Legolas, and in his fair elvish face there was great distress.
The first thing he ever said.
"...But I say : Let the ploughman plough, but choose an otter for swimming, and for running light over grass and leaf,
or over snow - an Elf."
"Farewell!" he said to Gandalf. "I go to find the sun!"
"I do not wish to go to Moria."
"I have not heard it was the fault of the Elves."
When he's arguing with Gimli over who's fault it was.
"Ai! Ai!" cried Legolas. "A Balrog! A Balrog is come!"
"There lies the woods of Lothlorien! That is the fairest of all the dwellings of my people. There are not trees like the trees of that land. For in the autumn their leaves fall not, but turn to gold. Not till the spring comes and the new green opens do they fall and then the boughs are laden with yellow flowers; and the floor of the wood is golden and golden is it's roof, and its pillars of silver, for the bark of the trees is smooth and grey. So still our songs in Mirkwood say. My heart would be glad if I were beneath the eaves of that wood, and it were springtime!"
"Lothlorien! Lothlorien! We have come to the eaves of the Golden Wood. Alas that it is winter!"
"A plague upon the stiff necks of dwarves."
"It is old, very old. So old that I almost feel young again, as I have not felt since I travelled with you children. It is old and full of memory. I could have been happy here, if I had come in days of peace."
"Five hundred times have the red leaves fallen in Mirkwood in m home since then, and but a little while does that seem to us."
"There are eyes! Eyes looking out from the shadows of the boughs! I never saw such eyes before."
"The sun is high," said Legolas. "All the others are up and doing. Come, Master Sluggard, and look at this place while you may!"
Legolas comes up with the nastiest nicknames doesn't he? "Master Sluggard" is what he calls Merry.
