Westworld Season 2 Trailer: It's Us Or Them

A new full-length trailer for Westworld season 2 has arrived, promising more secrets and mysteries, and a war between hosts and humans.

The brand new trailer for Westworld season 2 is here, heralding the critically-acclaimed HBO show's return in just a few weeks. Created by Jonathan Nolan and Lisa Joy, Westworld is based on the 1973 movie of the same name and set in a futuristic theme park where wealthy guests are invited to sin guilt-free among the park's collection of extremely lifelike androids, or "hosts."

The end of season 1 saw Westworld's hosts rise up against their oppressors in a bloody revolt, and season 2 will be a battle for control of the park - though if this trailer is anything to go by, don't expect all-out war and endless action scenes. It looks like Westworld season 2 will be just as cerebral as season 1, with the hosts still searching for meaning in their existence, and deciding what kind of people they are going to be. Maeve (Thandie Newton), for example, has taken Westworld's writer Lee Sizemore (Simon Quarterman) captive and is searching for her daughter - but her daughter has already been reprogrammed and is now a different character.

The main focus of the trailer, however, is Dolores (Evan Rachel Wood) and her continued search for answers. The opening dialogue between Dolores and (presumably) Arnold (Jeffrey Wright), along with Jimmi Simpson's return as William, demonstrates that we're not yet done with Dolores' exploration of her memories. Now that she knows the truth, and is free to roam the formerly off-limits areas of the park, she will no doubt uncover more secrets about Robert Ford (Anthony Hopkins) and Arnold's designs.

Bernard (Wright), meanwhile, is in a rather unique position, since the Delos security team fighting to take back the park don't know that he's a host. Wright has said that Bernard will be dealing with "cognitive challenges" in season 2, due to the fact that he was shot in the head in season 1, and that, like the other hosts, he is "aspiring to kind of an awakening" in the wake of discovering his true nature.

Finally, the trailer offers a tantalizing look at ShogunWorld, which we first glimpsed at the end of season 1. ShogunWorld is another theme park, adjacent to Westworld, with an Ancient Japan theme, and it seems as though the hosts of ShogunWorld will also be liberated. Perhaps Maeve is looking for an army.

The trailer is set to an instrumental cover version of Nirvana's "Heart-Shaped Box," promising even more haunting covers from Westworld composer Ramin Djawadi in season 2.
