The fourth and final season of the American science fiction dystopian television series Westworld, subtitled The Choice,[1] premiered on HBO on June 26, 2022, and concluded on August 14, 2022, consisting of eight episodes.

The fourth season stars an ensemble cast led by Evan Rachel Wood, Thandiwe Newton, Jeffrey Wright, Tessa Thompson, Aaron Paul, James Marsden, and Ed Harris.

Two decades later, Christina, a woman resembling Dolores who works at a video game company writing non-player character (NPC) storylines and backstories, gradually begins to question the nature of her reality after she realizes that it appears her stories are somehow translating to the lives of people in the real world.

Meanwhile, Bernard Lowe continues the mission left to him by Dolores, spending two decades simulating near-endless realities in the Sublime, where he hopes to find a path to saving both hosts and humanity.

[22] A first look at footage of the season was released on December 22, 2021, in an HBO Max 2022 sizzle reel, providing glimpses of returning characters played by Ed Harris, Thandiwe Newton, and Aaron Paul.

The website's critical consensus reads: "Westworld's continued reliance on mystery will frustrate just as much as it intrigues, but this fourth season still offers plenty of gleaming and menacing insight into a brave new world.
