Last August, just before the super-sized finale of True Detective Season 2, HBO debuted the first trailer for its splashy new sci-fi western drama, Westworld. Now after a rocky 2016 where production on the project was shut down, partially re-cast, and restarted, HBO is ready to give the series a whole new push and the network chose the splashy Game of Thrones “Battle of the Bastards” episode to launch the latest trailer.

The series is an updated version of Michael Crichton’s directorial debut film, Westworld, a cowboy-centric precursor to Jurassic Park. The titular Westworld is a futuristic theme park where instead of lab-created dinosaurs running amok, you have terrifying robotic cowboys, memorably played by Yul Brynner in the original 1973 film and here portrayed by a black-hatted Ed Harris.

Sir Anthony Hopkins is Dr. Robert Ford, the John Hammond to Harris’s velociraptor in cowboy boots. The cast is rounded out by Evan Rachel Wood, James Marsden, Thandie Newton, Jeffrey Wright, Sidse Babett Knudsen, Rodrigo Santoro, Shannon Woodward, Ingrid Bolsø Berdal, Ben Barnes, Jimmi Simpson, Clifton Collins, Jr., Lili Simmons, Simon Quarterman, and Angela Sarafyan. Wood’s character is described as “the quintessential farm girl of the frontier West — who is about to discover that her entire idyllic existence is an elaborately constructed lie.” I think it’s safe to say from this teaser that we can read that as “robot in a bonnet,” right? So look for a lot of existential ennui and meaty moral quandaries surrounding the dawn of artificial intelligence.

But keep your eye, most of all, on Harris. Though it’s been somewhat forgotten by time, the original Westworld film was actually a hit when it was originally released, and its pop-cultural influence stretches beyond its role as a blueprint for Jurassic Park. John Carpenter has said that the relentless, demonic Gunslinger inspired him to create Halloween’s Michael Myers, one of cinema’s most iconic horror figures. Is Ed Harris the new face of our nightmares? Or is a God complex-afflicted Hopkins the more likely candidate for modern monster in HBO’s latest star-studded creation? Westworld will premiere on HBO this fall.
