HBO war premiered Thursday with Dominic West and Sienna Miller playing the divorcing spouses at the center of War, an anthology series that turns a marriage split into the engine of the drama. The first installment puts Morgan Henderson, a tech mogul, opposite Carla Duval, a movie star, and sends their dispute through a legal process that is built to widen, not settle, the conflict.
The eight-episode series starts with a divorce that is already past the point of repair. Morgan and Carla have been married a long time and are growing apart, and the case is designed to move from mediation to arbitration to courtroom, which gives the show a procedural spine instead of a one-scene argument.
Taylor & Byrne versus Cathcarts
Taylor & Byrne represents Carla Duval, while Cathcarts takes Morgan Henderson. Nicholas Taylor and Serena Byrne head Taylor & Byrne, and they are married and expecting their first child, a detail that puts their own relationship beside the one they are litigating. At Cathcarts, St. John Smallwood is described as a self-satisfied vituperous bully, Beatrice Ubosi is more grounded, and David Schill is comparatively hapless.
The firms are part of the show’s first-installment structure, where law offices go head to head instead of a single family lawyer carrying the case. Taylor & Byrne is new, all glass and light; Cathcarts is dark wood and padded chairs. Those visual choices do the work a speech usually does: they tell you which side wants to look modern and which one wants to look entrenched.
Morgan Henderson and Flora Monroe
Morgan Henderson also sleeps with Flora Monroe, who is Carla Duval’s friend. Flora then presents Carla with an evidentiary Polaroid of Morgan and herself in bed, and the setup gets summed up in one line: “It’s a trap! A honeytrap.” That photo shifts the dispute from private damage into material a lawyer can use, which is the point at which a breakup becomes a case file.
“For all the talk about money, the lawyers’ cut never comes up.” That omission is the sharpest business note in the series. The case keeps pushing toward arbitration and courtroom, yet the money discussion never reaches the fee structure, which leaves the audience watching leverage, not billing, drive the action.
War and the MacGuffin
The review calls the divorce a MacGuffin, even though the case is also described as the central story that will drive the eight-episode run. That split is useful: the marriage break-up is the hook, but the legal steps are the machinery. In practice, the show is less interested in whether the couple can stay together than in how each stage of the dispute extracts a new advantage.
Carla Duval’s apartment is bright and high-ceilinged, with filigreed plaster moldings and inset tropical murals, while Morgan Henderson’s is stark and dark, with no sense of being lived in or enjoyed. The contrast is not decorative; it places the two sides of the divorce in different emotional economies before the arguments even start. How much of War is based on the real lives of Sienna Miller and Dominic West is not answered here, and that is exactly the point where the series keeps its most saleable question in reserve.
