It's a new world in the first season 3 Westworld trailer

Westworld creators Jonathan Nolan and Lisa Joy shared a whole host of details about the series’ upcoming third season in a recent interview with Entertainment Weekly, assuring viewers frustrated with its myriad of puzzle boxes that “this season is a little less of a guessing game.” Good, because it was starting to feel like the show existed only for people who liked to dissect it on Reddit (and, of course, our own critic, who mostly enjoyed the divisive second season).
The first teaser for the third season showed that a sea change is most definitely afoot: Breaking Bad’s Aaron Paul led the clip as a blue-collar worker and budding revolutionary in a futuristic L.A. who soon crosses paths with Evan Rachel Wood’s escaped host Dolores, the only established character to appear. In the interview, Paul’s character is identified as Caleb, and it’s said he has “a strong impact” on Dolores as she experiences “culture shock” in the world outside of the theme park.
