总结如下英文段落：“Blade Runner, directed by Ridley Scott and released in 1982, is an iconic science fiction film that explores themes of identity, humanity, and the consequences of technological advancement. Set in a dystopian future, the film follows Rick Deckard, a retired police officer, as he searches for and "retires" rogue replicants - bioengineered beings who have returned to Earth. Blade Runner's visual style and atmospheric lighting set it apart from other sci-fi movies of its time.”
