This post contains spoilers through the sixth episode of Westworld, "The Adversary." Head to Westworld World, our show hub, for recaps, theories, and deep dives.
Westworld pulls from a treasure trove of influences, including Michael Crichton (especially his original Westworld and Jurassic Park), open-world video games (in particular Red Dead Redemption), classic art and literature (Shakespeare, Alice's Adventures in Wonderland), philosophy (shout-out to Julian Jaynes' writings on the bicameral mind), and religion (so many biblical references) -- many of which get special shout-outs on screen and in dialogue.
"As a reformed gamer, I was fascinated in how any popular game is instantly scoured for mistakes or Easter eggs," series co-creator Jonathan Nolan told Entertainment Weekly in October. "That programmers quickly realized mistakes could be deployed as Easter eggs for the hardcore gamers who quickly work their way through the main narrative." We happily rewatched every episode of the show multiple times to find hidden references, in-jokes, and homages; our favorites are listed below.
