I lurves Riddick:
"Are you afraid of the dark? I'm not...the dark is afraid of me." -Riddick, Escape from Butcher Bay
"Trying to get under my skin already, Riddick?"
"It'd be easier...if I had something sharp." -Hoxie and Riddick, respectively, EFBB
"Let's play...who's the better killer?" -Riddick, EFBB
"You gonna kill me with your soupcup?"
"It's a teacup. I'm going to kill you with my teacup." -An inmate and Riddick, respectively, Chronicles of Riddick
"They say most of your brain shuts down in cryosleep. All but the primitive side, the animal side...guess that's why I'm still awake." -Riddick, Pitch Black
[getting into a knife fight with Johns while dark-dwelling creatures are all outside their little circle of green light] "Only one rule...stay in the light." -Riddick, Pitch Black

"You're not afraid of the dark, are you?" -Riddick, COR
He's just too cool. This one here's the epitome of geekiness:
"There have always been ghosts in the machine. Random segments of code, that have grouped together to form unexpected protocols. Unanticipated, these free radicals engender questions of free will. Creativity. And even the nature of what we might call the soul. Why is it that when some robots are left in darkness, they will seek out the light? Why is it that when robots are stored in an empty space, they will group together, rather than stand alone? How do we explain this behavior? Random segments of code? Or is it something more? When does a perceptual schematic become consciousness? When does a difference engine become the search for truth? When does a personality simulation become the bitter mote... of a soul?"
-Dr. Alfred Lanning, I, Robot
And who can forget The Princess Bride? Source of the world's best quotes:
Inigo: "Oh, you don't know, eh? Fezzik, jug his memory."
[Fezzik whacks the albino over the head and he collapses]
Fezzik: "Sorry, Inigo. I didn't meant to jug him so hard."
"Love is pain, highness! Anyone who says otherwise is selling something." -Man in Black
"Do you want me to send you back where you came from, huh? Unemployed? In GREENLAND?!" -Vizzini
"Don't rush me. You rush a miracle man, you get rotten miracles." -Miracle Max the Miracle Man
"You fool! You fell victim to one of the classic blunders, the most famous is never get involved in a land war in Asia, but only slightly less well-known is this: never go in against a Sicilian when death is on the line! Ha ha ha ha ha ha ha! Ha ha ha ha ha ha ha! Ha ha ha-" [keels over dead] -Vezzini
"Hello. My name is Inigo Montoya. You killed my father. Prepare to die." -Inigo
Man in Black: But, I promise I will not kill you until you reach the top.
Man in Black: That's VERY comforting, but I'm afraid you'll just have to wait.
Inigo: I hate waiting. I could give you my word as a Spaniard.
Man in Black: No good. I've known too many Spaniards.
