Do Androids Dream of Electric Sheep? inspired the film Blade Runner.

In Dick’s novel, Earth is damaged by war and ecological loss, while artificial animals and androids imitate life with unsettling precision. Rick Deckard hunts unauthorized androids, but the pursuit gradually turns into a test of empathy and personhood. Britannica notes that the novel was adapted as Blade Runner, while the source text shows why the story endures: its central mystery is not whether machines can look human, but whether humans can still recognize one another.
