HBO and the BBC have launched new legal dramas focusing on high-profile family law battles. This reflects a major surge in divorce-centered television programming across major networks. HBO introduced its anthology drama series War on Sky Atlantic, while the BBC scheduled the Manchester-based spin-off series The Split Up to highlight elite divorce proceedings within British family law.
Created by George Kay, known for his work on Lupin and Hijack, War details the messy marital breakdown between tech billionaire Morgan Henderson and international film star Carla Duval. Portrayed by Dominic West and Sienna Miller, the couple’s separation sparks an aggressive legal war between rival London law firms Cathcarts and Taylor & Byrne.
Inside the Plot and Rival Law Firms of HBO’s War
The logline for HBO’s new legal thriller promises high stakes, stating: “Two rival London law firms take on the case of the century. In a world of love, scandal, betrayal, and ambition, winning is everything. This is WAR.” The series debuted with an eight-episode first season on October 1, 2026, across HBO and HBO Max in the U.S., alongside international platforms like Sky in the United Kingdom.
Set in London, Season 1 tracks the explosive legal strategies deployed by rival firms Cathcarts and Taylor & Byrne. The cast features:
- Dominic West as Morgan Henderson, a wealthy tech entrepreneur.
- Sienna Miller as Carla Duval, his estranged movie-star wife.
- Phoebe Fox and James McArdle as Serena Byrne and Nicholas Taylor, married title partners at Taylor & Byrne.
- Nina Sosanya as Queen Beatrice “Queen Bea” Ubosi and Pip Torrens as St. John Smallwood, representing the Cathcarts firm.
- Archie Renaux as ambitious lawyer Johnny Warren.
Critical Reception and Global Streaming Success
Following its premiere, War quickly climbed streaming charts, ranking as a top-10 show globally on HBO Max and securing the No. 1 spot in Australia. Critics have generally praised the sharp writing and powerhouse performances. The series holds a Certified Fresh rating on Rotten Tomatoes, with reviewers highlighting the palpable chemistry between West and Miller.
TheWrap critic Deidre Johnson noted, “Miller and West put in stellar performances as Carla and Morgan, two people that still have love for each other and appear to have regrets.” Peter Travers added that the lead actors play off each other “with the skill of two sharks pretending they don’t smell the blood in the water.”
Looking Ahead to Season 2 and the BBC’s The Split Up
HBO has already ordered a second season of War. This upcoming season will shift focus from divorce proceedings to a high-profile defamation lawsuit. Season 2 has already added a stellar supporting lineup including Marisa Tomei as Avery Reed, Kelly Macdonald as Jo MacNeil, David Harewood as Jefferson Allen, and Richard Schiff as Elliott Wyatt.
