- War premieres October 1 on HBO and HBO Max; it is not streaming yet.
- The eight-episode first season releases weekly on Thursdays.
- Consider it for a legal drama built around a celebrity divorce and rival firms.
For an October HBO Max watchlist, War has a specific reason to make the cut: it turns a public divorce into a contest between powerful London law firms. Dominic West and Sienna Miller lead the cast, and creator George Kay brings the series to HBO and Sky. This is a preview recommendation based on the announced setup and official trailer, ahead of its premiere.

Who should put War on their list?
The first season centers on tech entrepreneur Morgan Henderson and movie star Carla Duval’s divorce, with Cathcarts & Sons and Taylor & Byrne fighting for their clients. That makes it a promising choice for viewers who like negotiations in which personal pride and public reputation can be as consequential as the formal case. The draw is watching both the clients and their representatives pursue victory, with several competing interests in the room.
Expect an ongoing case, not a weekend box set
HBO’s U.S. announcement confirms an October 1 debut on HBO and availability on HBO Max. It describes an eight-episode season with new installments on Thursdays. If you enjoy discussing shifting loyalties between episodes, that cadence may suit you. If you prefer to finish a whole story over a weekend, save the title for later and check the available episodes before starting. The announcement does not make it a complete-season launch.
Use the trailer to test the tone
The official trailer is the useful next step for deciding whether this legal drama belongs in your October queue. Pay attention to the balance of client conflict and rivalry between the firms: the series is pitched around an escalating, headline-making dispute. That is the audience fit behind this pick. As of September 21, the premiere is still ahead; no finished-season verdict or current streaming availability is implied. Bookmark it for October 1 if that kind of sustained legal battle appeals.
