The Blade Runner movies are set in a dystopian future where humanity has expanded beyond Earth and colonized other planets. The Earth is depicted as a bleak, polluted, and overcrowded place where most people live in poverty and misery.
The first Blade Runner movie is set in 2019, a time when artificial intelligence has advanced to the point where it is difficult to distinguish between humans and robots, known as replicants. Replicants are genetically engineered beings created to do the dangerous and undesirable work that humans no longer want to do. They have a limited lifespan of four years and are forbidden from returning to Earth.
