Fan Casting Do Androids Dream of Electric Sheep?

In 2021 following a devastating global war called World War Terminus, the Earth's radioactively polluted atmosphere leads the United Nations to encourage mass emigrations to off-world colonies to preserve humanity's genetic integrity. Moving away from Earth comes with the incentive of free personal androids: robot servants identical to humans. The Rosen Association manufactures the androids on a colony on Mars, but some androids violently rebel and escape to Earth, where they hope to remain undetected. As a result, American and Soviet police departments remain vigilant and keep android bounty-hunting officers on duty. On Earth, owning real live animals has become a fashionable status symbol, both because mass extinctions have made authentic animals rare and because of the accompanying cultural push for greater empathy. However, poor people can only afford realistic-looking robot imitations of live animals. Rick Deckard, the novel's protagonist, for example, owns an electric black-faced sheep. The trend of increased empathy has coincidentally motivated a new technology-based religion called Mercerism, which uses "empathy boxes" to link users simultaneously to a virtual reality of collective suffering, centered on a martyr-like character, Wilbur Mercer, who eternally climbs up a hill while being hit with crashing stones. Acquiring high-status animal pets and linking in to empathy boxes appear to be the only two ways characters in the story strive for existential fulfillment.
