HBO’s legal thriller series War chronicles a high-stakes London divorce between an actress and a wealthy tech billionaire. Created by George Kay, the eight-part drama features Dominic West and Sienna Miller as the parting couple whose split triggers an aggressive clash between two rival law firms.
The eight-part legal thriller series War made its premiere on Sky Atlantic, plunging viewers into the cutthroat world of elite British legal battles. Created by George Kay—whose previous writing credits include Lupin, Hijack, and The Long Shadow—the series follows the cataclysmic split between tech mogul Morgan Henderson (Dominic West) and Hollywood actress Carla Duval (Sienna Miller). What begins as a private marital breakdown quickly escalates into a public spectacle when both parties retain opposing legal counsel, setting off a bitter custody and property dispute that one attorney predicts will become the biggest divorce trial in British legal history.
Morgan Henderson and Carla Duval at the Center of the Split
Morgan Henderson built his massive fortune as the creator of Zephyr, a networking platform marketed around positive online interactions. Despite his public posturing about accountability and digital civility, Morgan displays a distinct lack of self-awareness regarding his personal life. West plays the tech tycoon with an arrogant bafflement
reminiscent of his past roles, struggling to see his own fingerprints on the unraveling of his marriage.
Across the breakfast table is Carla Duval, an A-list movie star whose professional fame is naturally beginning to wane as she ages. Before open hostilities break out, Carla orchestrates a honey trap, engineering an encounter between Morgan and a young stranger named Flora Monroe (Rose Williams) at a networking gala where Morgan is receiving the Pioneer of the Year Award. The setup provides Carla with the exact proof of infidelity she needs to activate her legal team.
Cathcarts Versus Taylor & Byrne in London Legal Battles
Carla counters by hiring Taylor & Byrne, a younger, contemporary firm featuring glass walls and stark strip-lighting, run by married attorneys Nicholas Taylor (James McArdle) and Serena Byrne (Phoebe Fox). While scrambling for employment, Johnny interviews at both firms and secures a position at Taylor & Byrne—while secretly operating as an inside man and double agent passing information back to Cathcarts.
London as the Global Capital of High-Stakes Divorces
The setting is intentional: London is widely acknowledged as the divorce capital of the world due to English courts maintaining a reputation for fairness, expertise, and financial generosity toward the weaker economic party.
That legal generosity has spawned an entire professional ecosystem of specialist law practices, private investigators, and forensic accountants. To prepare for his role, Dominic West consulted rich divorcees and listened to podcasts covering billionaire asset splits.
- Top divorce solicitors can charge an hourly rate of £1,200.
- Specialist barristers command fees up to £10,000 per hearing.
- Data from the Office for National Statistics indicates that couples divorcing in England and Wales had been married for an average of 13 years, creating deeply tangled shared assets involving homes, pensions, and children.
Critical Reception and Future Plans for the HBO Anthology
Critical response to the eight-part drama has highlighted its glossy production values alongside its narrative excesses. Reviewers note that while the series benefits from strong chemistry between West and Miller and an impressive supporting roster—including Celia Imrie as Taylor & Byrne attorney Budgie and Aran Murphy as Carla’s teenage son Gabriel—the main couple occasionally risks being sidelined by the mechanical ruthlessness of their legal representation.
Despite debates over whether the script fully balances the human tragedy of a family falling apart with the cartoonish glee of corporate backstabbing, HBO has already locked in future plans for the franchise. The anthology series is slated to return for a second season featuring a brand-new legal case starring Marisa Tomei and Kelly Macdonald.
