Any line delivered by Vin Diesel when playing Riddick
My personal favorites are:
The Chronicles of Riddick
Slam Guard: "You'll kill us... with a soup cup?"
Riddick: "Tea, actually."
Slam Guard: "What's that?"
Riddick: "I'll kill you with my teacup."
Pitch Black:
Paris: [Greets Riddick] "Paris P. Olgilvie. Antiquities dealer, entrepreneur."
Riddick: [Shakes hands with Paris] "Richard B. Riddick. Escaped convict. Murderer."
Riddick: [Upon finding out that an eclipse is coming] "You're not afraid of the dark are you?" [Riddick smiles mockingly]
Imam: "Shall we pray together? I have already prayed with the others."
[Riddick ignores him]
Imam: "It is painless."
Riddick: "It's pointless."
Escape From Butcher Bay (game)
Hoxie: "Already trying to get under my skin, Riddick?"
Riddick: "It'd be easier... if I had something sharp."
Abbott: "You're messin' with the natural order of things here, Riddick. As a result someone can get hurt. And we don't want that."
Riddick: "Speak for yourself."
[Riddick loses his assault rifle and resorts to getting into grabbing range on the prison guard. Both of them fall down a pit]
Riddick:[Shouting while falling] "It ain't the fall that gets ya."
Riddick:[Having landed on the guard, softening his landing and killing the guard] "It's the sudden stop at the bottom."
Riot Guard: "Prisoner! This area is restricted! What are you doing here?"
Riddick: "Oh. Heh. Sorry, my mistake."
Riot Guard: "Shit, you're Riddick!"
Riddick: "I think you're gonna need backup."
Riddick: [talking to guard] "The dark... you afraid? I'm not. The dark, is afraid of me."
