Westworld (Seasons 1–4)

Westworld is an HBO sci-fi Western you can watch online on iFILM — all four seasons, all 36 episodes. Created by Jonathan Nolan and Lisa Joy, the series launched in October 2016 and is set inside a sprawling theme park where android "hosts" play out scripted frontier narratives for paying guests who can do as they please with no consequences.

Then one host starts to remember. Evan Rachel Wood anchors the early seasons as Dolores, the park's oldest host slowly piecing together the truth about her own existence. Thandiwe Newton's Maeve runs a parallel arc — a saloon madam who begins rewriting her own code from the inside. Jeffrey Wright plays Bernard, a programmer whose relationship to the park turns out to be far more complicated than his job title suggests. Ed Harris, Tessa Thompson, and Aaron Paul all move through a story told across multiple timelines, with layers that only click into place episodes later.

Produced by Bad Robot and Warner Bros. Television, the show earned more than 50 Emmy nominations across its first two seasons and reshaped how audiences talked about AI, free will, and narrative structure on television. The series ran through 2022. Stream every season of Westworld online on iFILM.
