BLADE RUNNER, the film (1982). “The film 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.” The trick is to spot the replicants.
