Soon you’ll be able to visit Westworld, a kind of adult playground where artificial intelligence and a Spaghetti Western landscape fulfill your every desire imaginable. Before that happens, HBO released a new trailer for the upcoming drama series to remind us all how bad we want to go to there.

A Pixar-esque piano melody accompanies the dreamy imagery before the trailer rips us out of there. In it we see Anthony Hopkins evaluating one of the A.I., played by Evan Rachel Wood, as well as James Marsden, Ben Barnes, and Jimmi Simpson enjoying enjoying their own personal fantasies.

The fantasy, however, ends abruptly when the music turns to Ray Orbison’s “In Dreams” and the robots built to satisfy their urges become more self-aware. That’s the general concept, which is based on the Westworld film from 1973 that was written and directed by novelist Michael Crichton. Some of the creations break free of their makers’ hold and start killing visitors of Westworld. Much like a dream you try to remember the next morning, the new footage cuts between fantasy and reality, peace and horror, robot and human until everything you think you know is brutally dashed.

Watch the trailer below:

Also featured in the series are Ed Harris (The Adderall Diaries), Thandie Newton (The Slap), Jeffrey Wright (The Hunger Games films), Tessa Thompson (Thor: Ragnarok), Sidse Babett Knudsen (Inferno), Rodrigo Santoro (300: Rise of an Empire), Shannon Woodward (Raising Hope), Ingrid Bolsø Berdal (Hercules), Simon Quarterman (The Devil Inside), Angela Sarafyan (The Immigrant), Luke Hemsworth (the other Hemsworth brother), and Clifton Collins, Jr. (Triple 9).

The dream will begin on October 2. Here’s the official description:

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