HBO hasn't officially renewed Westworld for Season 2 yet, but showrunner Jonathan Nolan says they're already planning the story for the show's inevitable pickup. During the show's panel at New York Comic Con, Nolan admitted that one of the toughest parts of the season was figuring out what to cut from each episode, since they ended up with so much interesting material thanks to the actors' performances. "There were a handful of things that we weren't able to touch in the first season; we're now currently breaking the second season," he told fans. "One of the really nice things about TV is, you get to go again."
