HBO confirmed in 2020 that it would make a fourth season of Westworld. The third season ended in May of that year, and despite a steep decline in viewership, the studio said showrunners Jonathan Nolan and Lisa Joy would be back to continue their big-budget sci-fi drama. Here, then, is everything you need to know about the upcoming season of Westworld.

Westworld season 4: What to know

There are spoilers below.

Based on the 1973 movie directed byJurassic Parkauthor Michael Crichton, Westworld is a drama series that, for the first two seasons, was set in an android theme park designed to look like the West. Season three spent more time in the human world, and it’s expected season four will continue down that path, picking up existing storylines.

Keep in mind Westworld season three ended with[spoiler]Aaron Paul’s Caleb beginning a revolution, and it focused on Bernard’s journey to understand the Sublime, a secret server to which some hosts have escaped. Caleb will likely continue the revolution in place of Dolores Abernathy (Evan Rachel Wood), who died at the end of season three. The fate of Dolores still seems unknown, however. Although Serac - a now-dead crazy trillionaire whose AI controlled humanity - deleted Delores' memories, all hosts need to perish for her to truly be dead.
