WESTWORLD Season 2 Official Trailer #2

Check out the newest trailer for HBO’s second season of Westworld!

Created by Jonathan Nolan and Lisa Joy, the first season of Westworld adapted Michael Crichton’s 1973 film into a sprawling, ambitious look at artificial intelligence, corporate greed, and the very idea of what it means to be human. It also adopted a unique puzzle box format, featuring multiple timelines that were cross-cut against one another, leaving it unclear to many viewers until late in the season that some characters were actually younger versions of others — with the entire thing tied together by the ageless robotic hosts themselves. That same playful sense of mystery permeated the narrative as well, with Harris’ Man in Black caught in a never-ending search for what he called “the center of the maze.”

The maze didn’t end up being quite the surprise the character was looking for, but judging from early indications, the big mystery in the second season is going to be something called “the door.” In fact, in a recent interview with EW, Nolan revealed that “The Door” was the secret internal codename he and Joy used for the new season. (The codename for the first season was, yes, “The Maze.”) In the world of Westworld, of course, what all of that actually means will no doubt end up being the polar opposite of what fans expect — but then again, that’s part of the allure. The new season of Westworld debuts on April 22nd.
