War, a British legal thriller headlined by Sienna Miller and Dominic West, lands on HBO Max in France on Friday, October 2, 2026. The first season comprises eight episodes.
Carla Duval, an international film star, has filed for divorce from her husband Morgan Henderson, a powerful British entrepreneur. Their split quickly becomes a public affair, with Cathcarts & Sons and Taylor & Byrne ready to pull out all the stops to push their client’s case.
The ambitious Jonathan "Johnny" Warren finds himself swept into the fierce rivalry between the two firms. Behind the division of the fortune and the couple's image war, the series probes power dynamics, internal betrayals, and the tactics lawyers employ where winning comes first, above all else.
Sienna Miller and Dominic West headline alongside Archie Renaux, Phoebe Fox, James McArdle, Nina Sosanya, Pip Torrens, Celia Imrie, Nick Mohammed, Emma Laird and Archie Panjabi.
The series is created by George Kay, the writer behind Lupin and Hijack, and directed mainly by Ben Taylor. Commissioned for two seasons, War will present a new case in its next installment, headlined by Marisa Tomei, Kelly Macdonald and David Harewood.
