Attendees of the CBS Person of Interest panel at Comic-Con got more than they bargained for when executive producer Jonathan Nolan aired a teaser trailer for his newest show, Westworld.

Billed as an adaptation of the 1973 Michael Crichton film, Westworld is a sci-fi show that focuses on a theme park with androids, which act out any fantasy the visitors can think of - no matter how dark or twisted. Though the trailer has yet to appear online, new images from the show have now been released, featuring both the Wild West world inhabitants - like Ed Harris, James Marsden, Thandie Newton, and Evan Rachel Wood - and the people who work behind the scenes - like Anthony Hopkins and Jeffrey Wright.

Check them out below:

Developed and exec produced by Nolan with his wife, Lisa Joy (Pushing Daisies), Westworld also lists JJ Abrams and Bryan Burk as executive producers since and their company, Bad Robot Productions, are behind the project. Anthony Hopkins stars as Dr. Robert Ford, the theme park owner while Ed Harris takes on the role of android Gunslinger, played by Yul Brynner in the original film. Evan Rachel Wood (True Blood), James Marsden (X-Men), Thandie Newton (The Pursuit of Happyness) also star as inhabitants of a Wild West world which is really just a simulated part of the high-tech theme park. And, finally, Jeffrey Wright (Mockingjay) plays Bernard Lowe, the "creator of the artificial people."

Joy describes the show as a "sci-fi mashed up with a western," while Nolan says, "It’s a place where you can be whoever you want to be and there are no consequences - no rules, no limitations."

Nolan also states that it's the team's intention to make "the most ambitious, subversive, f–ked-up television series."

Westworld filmed last year and was ordered to series after a successful pilot. Though it was expected to make its premiere in 2015, it's been pushed back to an unconfirmed date in 2016, with the explanation being that they needed more time to ensure each episode matched up to the quality of the pilot.

By all accounts, the teaser shown at Comic-Con previewed a dark and gripping show, with an unseen voice asking Wood’s character, Dolores, if she wants to wake up from this world. Though the images feature stunning scenery, they do definitely foreshadow unease and give a sense of all not being what it seems. One suspects that Dr. Ford (Hopkins) might be behind a lot of the distress caused.

Westworld will air on HBO in 2016
