WAR Legal Drama Premieres on HBO and Sky

The divorce battle pits two specifically named London firms against each other: Cathcarts & Sons and Taylor & Byrne, led by Serena Byrne and Nicholas Taylor, respectively.
WAR is produced by Banijay-owned New Pictures and Observatory Pictures, with Ben Taylor serving as lead director and Laurie Borg as series producer.
The ensemble includes Phoebe Fox, James McArdle, Nina Sosanya and Pip Torrens, alongside a larger supporting cast that includes Archie Panjabi, Nick Mohammed, Celia Imrie and Adrian Scarborough.
Season two is already in production and will feature Marisa Tomei, Kelly Macdonald and David Harewood in the next legal storyline.
Miller’s premiere gown came from Dilara Fındıkoğlu’s fall 2023 collection, which the designer described as being about “a woman possessing her body back,” influenced in part by the Iranian protests.
HBO and Sky have released the full trailer for WAR, an eight-part legal drama premiering October 1 on HBO and October 2 on Sky and NOW. The series stars Sienna Miller and Dominic West as a film star and tech entrepreneur locked in a bitter divorce battle between two rival London law firms: Cathcarts & Sons and Taylor & Byrne. Created by George Kay, WAR follows young lawyer Johnny Warren as ambition and betrayal reshape his legal career.
Miller and West appeared friendly at the London premiere despite portraying an estranged couple. Miller wore a dramatic black feathered gown from Dilara Fındıkoğlu's fall 2023 collection and was joined by her teenage daughter, Marlowe Sturridge. Sky has already renewed WAR for a second season, converting it into an anthology series focused on a new defamation case.
The story centers on a messy split between a famous film star and a tech entrepreneur. Two powerhouse London law firms clash over the case: Cathcarts & Sons faces off against Taylor & Byrne, led by Serena Byrne and Nicholas Taylor. Geektown reports the series explores the high-stakes world of celebrity divorce litigation, where winning means everything and collateral damage is inevitable.
The ensemble cast brings depth to the legal drama. Beyond Miller and West, the show features Phoebe Fox, James McArdle, Nina Sosanya, Pip Torrens, Archie Panjabi, Nick Mohammed, Celia Imrie, and Adrian Scarborough. Nerdtropolis notes that Archie Renaux plays Johnny Warren, a young lawyer navigating ambition and betrayal as his career unfolds within this toxic legal environment.
WAR is produced by Banijay-owned New Pictures and Observatory Pictures, with veteran director Ben Taylor steering the series and Laurie Borg serving as series producer. Radio Times highlights the ambition behind the project—crafting a prestige legal drama that rivals hit courtroom shows. The eight-part structure allows room for complex character arcs and intricate legal maneuvering across the first season.
Sky wasted no time committing to WAR's future. Season two is already in production and will pivot to a fresh defamation case, featuring Marisa Tomei, Kelly Macdonald, and David Harewood. This anthology approach allows the show to explore different legal battles and characters each season while maintaining the same universe and themes of corruption and power struggles.
