Watch Teaser for HBO's Sci-Fi Western Inspired by Red Dead Redemption, BioShock

HBO has released the first teaser trailer for Westworld, its upcoming sci-fi Western series starring Anthony Hopkins and Ed Harris. The trailer is quite creepy and alluring, giving us a first look at the re-imagining of the 1973 Michael Crichton movie.

"Have you ever questioned the nature of your reality?" reads a line from the show's description.

The show is being led by Jonathan Nolan, the creator of Person of Interest. He also co-wrote a number of movies with his brother, Christopher Nolan, including The Dark Knight Rises and Interstellar.

J. Nolan told Esquire writer Matt Patches last year that video games Red Dead Redemption and BioShock were two of his inspirations for Westworld.

HBO isn't giving away too many details at the moment, but describes Westworld as "a dark odyssey about the dawn of artificial consciousness and the future of sin."

The show, which debuts in 2016, also stars Evan Rachel Wood, James Marsden, and Jeffrey Wright.
