'Westworld' Season 1 Spoilers: Why Creators Don't Want To Reveal Who's Human And Robot

Before HBO's new sci-fi drama "Westworld" hits the small screen, fans already know of certain characters who are robotic "hosts." But as for the other characters, show creators Jonathan Nolan and Lisa Joy would rather have fans determine for themselves whether they are humans or hosts. Evan Rachel Wood's character Dolores Abernathy has already been outed as a host, but the actress told the L.A. Times that fans would have a difficult time guessing the identities of other Westworld mainstays. "It's a show you really want to pay attention to while you're watching it. I think when this series is done, your DVRs are going to break because everyone is immediately going to go back and re-watch the whole thing, and it will probably be better the second time," she said.
