BLADE RUNNER depicts a dystopian Los Angeles in which genetically engineered replicants, which are visually indistinguishable from adult humans, are manufactured by the powerful Tyrell Corporation. The use of replicants on Earth is banned and they are exclusively utilized for dangerous or menial work on off-world colonies. Replicants who defy the ban and return to Earth are hunted down and killed (“retired”) by special police operatives known as “Blade Runners”. The plot focuses on a group of recently escaped replicants hiding in L.A. and the burnt-out expert Blade Runner, Rick Deckard (Harrison Ford), who reluctantly agrees to take on one more assignment to hunt them down.
“Ridley really knew how to appeal to the art department, he was very wise about it. What he would say, up in the art department : ‘If you build it, I’ll shoot it.’ And who could resist the temptation of that? Because we’ve all suffered, making films with gigantic sets, and beautiful sets, and [all that is shown/shot are] talking heads. And that was disappointing. But because [Ridley] was an art director, he knew he could hook us with that bait. And he did it – if we built it, he shot it.” – Lawrence G. Paull, Production Designer
