'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. Everything means something. 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.

But as for James Marsden’s cowboy Teddy Flood, his human status remains uncertain. The actor earlier told Entertainment Weekly that the series is definitely going to deliver because producers made certain everything was all mapped out for years to come even before airing the first season.

“It wasn’t about getting the first 10 [episodes] done, it was about mapping out what the next five or six years are going to be,” said Marsden. “We wanted everything in line so that when the very last episode airs and we have our show finale, five or seven years down the line, we knew how it was going to end the first season – that’s the way [show creator] Jonah [Nolan] and [executive producer J.J. Abrams] operate.”

“Westworld” will be released on HBO on Sunday, Oct. 2 at 9 p.m. ET, reported Variety. Aside from Wood and Marsden, other stars of the show include Anthony Hopkins, Ed Harris, Jeffrey Wright, Thandie Newton, and Tessa Thompson, among many others.
