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

  • Westworld season 4 number of episodes: Eight episodes

There are spoilers below.

Based on the 1973 movie directed by Jurassic Park author 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. 

As for other storylines, expect Maeve (Thandiwe Newton) to continue her search for her daughter, and Charlotte Hale (Tessa Thompson) to continue building her host army. Humanity will also likely further descend into anarchy in season four. 

Things to remember before season four

There are spoilers below:

  • Dolores sacrificed herself - deleting all her memories - to save humanity.
  • Maeve and Caleb, who once opposed each other thanks to the war between Dolores and Seric, have teamed up to defeat Serac and shut down Rehoboam, an AI system.
  • Speaking of Caleb, he is an Outlier, as are Sera's brothers and many others.
  • And although William was killed by a host version of himself, he will play the host version of Man in Black under the control of the Chalores.
  • Chalores, who is building an army of hosts, also killed Hector, or crushed his control unit and destroyed his consciousness.
  • The Sublime, or the Valley Beyond, is an encrypted virtual world where hosts can live separately from humans.
  • The encryption key to Subline is in the mind of Bernard, who entered Sublime.
  • Teddy is also in the Sublime, and he will reprise his role in season four.
  • As for Stubbs, Clementine, and Hanaryo, they are hosts in the outside world.
  • Delos Destinations were shut down, and the hosts left behind were destroyed.
