Man there are tons. Not all necessarily hold meaning to life or anything, but sounded pretty epic in the movies.

Many of these are also book quotes...adaptations y'know. (I cheat!)
"What can men do against such reckless hate?" -Theoden (LotR)
"To look almost pretty is an acquisition of higher delight to a girl who has been looking plain for the first fifteen years of her life than a beauty from her cradle can ever receive." Northanger Abbey
"My idea of good company is the company of clever, well-informed people who have a great deal of conversation; that is what I call good company." -Anne (Persuasion)
"Life seems but a quick succession of busy nothings." Fanny (Mansfield Park)
"If I loved you less, I might be able to talk about it more. " -Knightly (Emma)
"I cannot speak well enough to be unintelligible." -Catherine (Northanger Abbey)
"Whether by the sword or the slow decay of time, Aragorn will die. And there will be no comfort for you. No comfort to ease the pain of his passing. He will come to death, an image of the splendor of the kings of men in glory undimmed before the breaking of the world. But you, my daughter, you will linger on in darkness and in doubt, as nightfall in winter that comes without a star. Here you will dwell, bound to your grief, under the fading trees, until all the world is changed and the long years of your life are utterly spent. Arwen, there is nothing for you here... only death." -Elrond (LotR)
"Oh, but you are alone. Who knows what you've spoken to the darkness, in the bitter watches of the night... when all your life seems to shrink, the walls of your bower closing in about you... a hutch to trammel some wild thing in. So fair. So cold. Like a morning of pale spring still clinging to winter's chill." -Grima Wormtongue (LotR)
"Where is the horse and rider,
Where is the horn that was blowing
They have passed like rain on the mountain
Like wind in the meadow
The days have gone down in the West,
Behind the hills, into Shadow
How has it come to this?" -Theoden King (LotR)
"I've seen things you people wouldn't believe. Attack ships on fire off the shoulder of Orion. I've watched C-beams glitter in the dark near the Tannhauser Gate. All those moments will be lost in time, like tears in the rain." -Batty (Bladerunner)
