War Season 1 on HBO Max: Full Release Schedule and Episode Dates

War, the starry HBO legal drama led by Sienna Miller and Dominic West, premieres in the United States on Thursday, October 1, 2026, on HBO and HBO Max. The eight-episode first season then releases one new chapter every Thursday, with the finale set for November 19, 2026.

New episodes arrive on HBO Max at 9 p.m. ET / 6 p.m. PT, in step with the cable premiere on HBO (9/8c). This is not a binge drop: after the October 1 opener, you get a single episode each week for eight weeks. Below is the complete week-by-week schedule, followed by everything you need to know about the cast, the story, and the anthology plan already in motion.

War Season 1 release schedule on HBO Max

All eight episodes stream on HBO Max in the US the same night they air on HBO. Each installment lands on Thursday at 9 p.m. ET / 6 p.m. PT.

HBO has not released individual episode titles ahead of the premiere, so the table sticks to confirmed dates. Expect this schedule to hold: HBO rarely deviates from a straight weekly Thursday cadence once a drama launches.

What is War about?

The first season turns a single, very public divorce into a courtroom bloodsport. Morgan Henderson (Dominic West), a British tech entrepreneur, and Carla Duval (Sienna Miller), an internationally famous film star, decide to end their marriage — and their split is handed to two rival London law firms, Cathcarts & Sons and Taylor & Byrne, that will do almost anything to win. Public image, money, and legal strategy quickly become the same weapon.

The show is created by George Kay, the writer behind the Netflix hit Lupin and the thriller Hijack, and it is built as an anthology: each season takes on a new case rather than continuing the same story. Junior lawyer Johnny Warren (Archie Renaux) is the audience’s way in, learning how power really moves through these elite firms.

Who is in the cast?

Dominic West and Sienna Miller headline, but the ensemble is deep. The confirmed cast includes:

• Dominic West as Morgan Henderson
• Sienna Miller as Carla Duval
• Archie Renaux as Johnny Warren
• Phoebe Fox as Serena Byrne
• James McArdle as Nicholas Taylor
• Nina Sosanya as Beatrice “Queen Bea” Ubosi
• Pip Torrens as St. John Smallwood
• With Nick Mohammed, Celia Imrie, Emma Laird, and Honor Swinton Byrne

Is War already renewed?

Yes. A second season was ordered before the first even reached viewers. In keeping with the anthology format, Season 2 will move to a new central case — a high-stakes defamation battle — with a fresh cast reported to include Marisa Tomei, Kelly Macdonald, and David Harewood. There is no release window for that season yet.

How to watch War in the US

War streams on HBO Max, which starts at $9.99 a month for the ad-supported plan in the US. Every episode is also broadcast on the HBO cable channel at 9 p.m. ET, so a cable or live-TV package that carries HBO works too. The series is produced by New Pictures and Observatory Pictures for HBO and the UK broadcaster Sky, which airs it in Britain a day later.
