Ok, this is an awesome thread, and i had to put in my two cents
“It was beauty killed the beast” classic line from King Kong
“Even the smallest person can change the course of the future” LOTR Fellowship of the Ring (that was my yearbook quote my senior year)
And of course, probably my favorite exchange from The Two Towers (Extended version)
(Legolas walks up to Gimli)
Legolas: Final count; forty-two
Gimli: Forty-two? That’s not bad for a pointy eared Elvish Princeling. (*Chuckles*) I myself am sitting pretty on forty-three.
Legolas: (*pulls out an arrow and shoots the ork between Gimli’s legs*) Forty-three.
Gimli: He was already dead.
Legolas: He was twitching.
Gimli: He was twitching, ’cause he’s got my axe embedded in his nervous system!
That still makes me laugh whenever i hear it.
