The Voight-Kampff Quiz: How Much Do You Know About 'Blade Runner'?

"I got four skinjobs walkin' the streets," Bryant tells Deckard.

Leon puts a bullet in Holden when he realizes Holden has found out Leon is one of the escaped replicants.

Bryant tells Deckard there are six renegade replicants, one of which already got killed. Who the remaining five are is open to a lot of fun conjecture (and is partly due to inconsistent script changes and an error in dubbing dialog which is fixed in some versions).

Replicants are given uncircumventable four-year life spans, because beyond that time they might begin to develop emotions and become indistinguishable from humans.

"Wake up. Time to die."

Rachael shoots Leon in the head just as he's about to put his fingers through Deckard's eye sockets.

They have an ongoing game of chess. Sebastian has only ever beaten Tyrell once.

All attempts to alter the lifetime-limiting genetic code causes a mutation or virus that kills the replicant.
