Fans who attended the Person of Interest panel at Comic-Con on Saturday were given a surprise treat, the first trailer for HBO's Westworld. While it may seem odd for an HBO trailer to debut during a CBS panel, Person of Interest creator Jonathan Nolan also co-created Westworld, which has been confirmed to debut sometime in 2016 on HBO. The network hasn't released the first trailer yet, but the show's https://twitter.com/WestworldHBOTV|Twitter page did debut four new photos, featuring series stars James Marsden, Anthony Hopkins, Thandie Newton, Ed Harris and Jeffrey Wright.

The Hollywood Reporter reveals that the Westworld trailer shown at SDCC opens with an "ominous character voiceover" saying, "Bring her back online. Have you ever questioned the nature of your reality?" Anthony Hopkins' character is also briefly featured in scenes that, like the photos below, depict a Western setting. The series is based on the 1973 film by Michael Crichton, which is set at a futuristic resort where wealthy patrons can visit recreations of different time periods and experience their wildest fantasies with life-like robots.

The series also stars Ingrid Bolsø Berdal, Miranda Otto, Simon Quarterman, Ben Hicks and Jeremy Hovan, alongside James Marsden, Anthony Hopkins, Thandie Newton, Ed Harris and Jeffrey Wright. HBO hasn't announced when in 2016 the show may debut, so stay tuned for more updates. In the meantime, check out these new photos from Westworld below.
