HBO has renewed WESTWORLD for a 10-episode second season.

However the show may be delayed until 2018: “Westworld is such a big, ambitious show. I don’t know if it will be fall of 2017 or into ’18,” HBO programming president Casey Bloys told The Hollywood Reporter. “That will depend as we get up and running. With Westworld, because the production is such a big endeavor, I don’t exactly know when [it will premiere] yet.

Season-to-date, WESTWORLD is averaging a gross audience of 11.7 million viewers, outperforming “Game of Thrones” and “True Detective” during similar times in their first seasons. DIVORCE and INSECURE are averaging 4.4 million and 3.2 million viewers, respectively, on par with other HBO half-hours like “VEEP” and “Girls.”

Set at the intersection of the near future and the reimagined past, the drama series WESTWORLD is a dark odyssey about the dawn of artificial consciousness and the evolution of sin, exploring a world in which every human appetite, no matter how noble or depraved, can be indulged.

WESTWORLD kicked off its ten-episode first season Oct. 2 on HBO, debuting hour-long episodes Sundays at 9:00 p.m. (ET/PT). Created for television by Jonathan Nolan & Lisa Joy, both of whom executive produce and write, with Nolan directing, the series is based on the 1973 film “Westworld,” written by Michael Crichton.

The cast for the first season of WESTWORLD includes Anthony Hopkins, Ed Harris, Evan Rachel Wood, James Marsden, Thandie Newton, Jeffrey Wright, Tessa Thompson, Sidse Babett Knudsen, Jimmi Simpson, Rodrigo Santoro, Shannon Woodward, Ingrid Bolsø Berdal, Ben Barnes, Simon Quarterman, Angela Sarafyan, Luke Hemsworth and Clifton Collins, Jr.
