The second episode of HBO's new sci-fi/western Westworld is now available on the network's streaming apps. This is ahead of schedule, as the episode was scheduled to arrive this Sunday, October 9 at 9 PM ET.

The episode is titled "Chestnut." According to EW, HBO might have released the episode early so as to avoid a clash with this Sunday's second presidential debate between Donald Trump and Hillary Clinton.

The first episode of Westworld, which aired on October 2, drew a reported 3.3 million viewers, making it the best start for an HBO drama since True Detective.

Critics recently posted their reviews for the first four episodes; reviews are mostly positive. There will be 10 episodes in Season 1, airing every Sunday evening at 9 PM on HBO.

Westworld stars Anthony Hopkins, Ed Harris, Evan Rachel Wood, James Marsden, and Thandie Newton. As mentioned, it's based on Crichton's 1973 movie of the same name.
