There's Something Wrong With Westworld in New Season 1 Trailer

Sunday marked the debut of HBO's sci-fi thriller "Westworld," set in a futuristic amusement park that invites wealthy guests to live out their greatest fantasies with android "hosts." Those androids are programmed to be non-violent, but as this extended season trailer shows, there may be errors in their original programming that allow them to learn they're living in a virtual world.

The trailer follows robotic host Dolores Abernathy (Evan Rachel Wood) as she begins to unravel the clues behind her artificial life. Dr. Robert Ford (Anthony Hopkins), the creator of Westworld, claims the hosts are under his control, but questions arise about how much autonomy the androids really have.

The mysterious Man in Black, portrayed by Ed Harris, is a guest who appears to be investigating the deeper game being played in the park. Designs are carved into the dirt, in what looks like a map. But where does it lead?

Thandie Newton's Maeve Millay, another Westworld host, narrates to close out the trailer: "You think I'm scared of death? I've done it a million times. I'm great at it. How many times have you died?"

Based on the 1973 film of the same name by Michael Crichton, "Westworld" was developed by Jonathan Nolan and Lisa Joy, along with executive producers J. J. Abrams and Bryan Burk. It airs Sundays at 9 p.m. ET/PT on HBO.
