Blade Runner
Directed by Ridley Scott, 1982. Based on Philip K. Dick’s Do Androids Dream of Electric Sheep? (1968). Neo-noir science fiction set in Los Angeles, November 2019. Shot by Jordan Cronenweth. Music by Vangelis.
Premise
Rick Deckard (Harrison Ford) is a retired blade runner — a special LAPD operative who hunts and “retires” replicants: bioengineered synthetic humans built by the Tyrell Corporation for dangerous off-world labour. He is recalled to track four escaped Nexus-6 replicants.
The replicants
| Name | Model | Role | Actor |
|---|---|---|---|
| Roy Batty | Nexus-6 | Combat; mission leader | Rutger Hauer |
| Pris | Nexus-6 | Basic Pleasure Model | Daryl Hannah |
| Zhora | Nexus-6 | Trained for political homicide | Joanna Cassidy |
| Leon | Nexus-6 | Soldier / menial labour | Brion James |
All four have a 4-year lifespan by design — a failsafe against emotional development.
The Voigt-Kampff test
Measures involuntary physiological responses (pupil dilation, capillary blush) to morally charged scenarios. Tests for empathy — which replicants lack in full. The test can take 20–30 questions for a normal human; a replicant might need 100+ before detection.
HOLDEN: You're watching television. Suddenly you realise there's a wasp
crawling on your arm.
LEON: [pause]
HOLDEN: It's hot. You're not wearing a shirt. You go to the kitchen
to get a drink of water. A chair.
LEON: I'd put my hands over it.
HOLDEN: The wasp crawls on the table.
LEON: Give it a finger.
HOLDEN: You'd be irritated?
LEON: I'd kill it.
Tears in rain
“I’ve seen things you people wouldn’t believe. Attack ships on fire off the shoulder of Orion. I watched C-beams glitter in the dark near the Tannhäuser Gate. All those moments will be lost in time, like tears in rain. Time to die.”
Rutger Hauer wrote “like tears in rain” himself, the night before filming. He also cut large sections of the original monologue. It is widely considered the finest death speech in science fiction cinema.
Is Deckard a replicant?
Ridley Scott says yes. Harrison Ford says no. Philip K. Dick, who died before the film’s release, said he didn’t know. The theatrical cut leaves it ambiguous. The Director’s Cut (1992) and Final Cut (2007) add a unicorn dream sequence that implies Gaff knows Deckard’s innermost thoughts — suggesting an implanted memory, suggesting a replicant.
The ambiguity is the point. The film isn’t really about whether Deckard is artificial. It’s about whether Roy is real.
