HBO invested $100 million in its re-imagining of Michael Crichton's 1973 directorial debut film "Westworld," and based on Sunday's debut it's off to a pretty solid start. The series premiere drew more than 3 million viewers, the pay cable network's largest debut since "True Detective," and those viewers don't have to wait a full week for another fix. HBO has released the second episode more than two days ahead of schedule to avoid losing viewers to the upcoming Presidential debate between Hillary Clinton and Donald Trump, according to Entertainment Weekly. The new episode, titled "Chestnut," can be viewed now via HBO Now, HBO Go and HBO On Demand.

HBO's "Westworld" takes place in a theme park of the same name as human guest explore a virtually recreated western setting that is populated by synthetic androids called Hosts. Guests essentially get to live out their fantasies -- violent, sexual, or otherwise. The original 1973 film followed a similar formula that Michael Crichton implemented in "Jurassic Park": The theme park malfunctions in some way and the park's attractions retaliate against guests.

"Westworld" was created for television by Jonathan Nolan and Lisa Joy and stars Anthony Hopkins, Evan Rachel Wood, Thandie Newton, James Marsden and Ed Harris. It normally airs on Sundays at 9pm, and the schedule change was first announced on Westworld's interactive promotional website Discoverwestworld.com.
