Blade Runner bears about as much resemblance to the book that inspired it as a box of chicken nuggets does to a live chicken, but in this case that’s probably a good thing. Do Androids Dream of Electric Sheep? was a singularly strange story, puzzling on many levels. (If you’re interested, you can check out my review of Electric Sheep here.)
Harrison Ford plays Rick Deckard, a former Blade Runner (aka, police bounty hunter) who’s been forced back into service to hunt down a group of escaped Nexus 6 androids, now referred to as replicants.
The plot and world-building of Electric Sheep has been pared down significantly in some aspects and completely rewritten in others. No mention is made of the massive nuclear war that made most of Earth uninhabitable, although the off-world colonies remain. Replicants, produced to provide slave labor on the colonies, periodically escape and make their way back to Earth.
