VOIGHT KAMPF TEST (Blade Runner)

          Tyrell: [Offscreen]  Is this to be an empathy test?

[Tyrell appears at the other end of the room, walks towards the two]

Tyrell: Capillary dilation of the so-called blush response...fluctuation of the pupil...involuntary dilation of the iris.

Deckard: We call it Voight-Kampf for short.

Rachael: Mr. Deckard, Dr. Eldon Tyrell.

Tyrell: Demonstrate it. I want to see it work.

Deckard: Where's the subject?

Tyrell: I want to see it work on a person. I want to see a negative before I provide you with a positive.

Deckard: What's that going to prove?

Tyrell: [Smiling] Indulge me.

Deckard: On you?

Tyrell: [Nods at Rachael] Try her.
