HBO has released the first trailer for “War” and it sells one divorce across its entire hundred and seven seconds. The cut opens on a question and comes back to it twice. Why are we getting a divorce? What the trailer never tells you is that this show is an anthology that changes its case every season, and the divorce on screen is only the first one.
The series premieres on 1 October with HBO carrying it in the United States and Sky carrying it in the United Kingdom, and the first season runs eight episodes. George Kay created it and Ben Taylor directs. Warning beyond this point there are spoilers for the “War” trailer, including who is suing whom, the leak that cracks one firm open, the shape of the format HBO has chosen not to mention, and the line the trailer uses to tell you exactly what kind of lawyers these are.
What the trailer never tells you is that this show is an anthology that changes its case every season, and the divorce on screen is only the first one.”
Start with the card, because it is the most honest thing in the trailer. Fifteen seconds from the end, over a dark interior, white capitals read FROM THE CREATOR OF LUPIN AND HIJACK. HBO is not selling a premise with that card and it is not selling a cast either. It is selling George Kay by name, which is a rare move for a legal drama and a direct statement about who the network thinks is watching.
We published the “Lupin” Part 4 trailer three days before this one landed, so the name is fresh on this site. Kay built that show and he built “Hijack,” which locked Idris Elba inside a plane for seven real-time hours. Both are high-concept thrillers with a clock running down in the corner of the premise. A divorce trial has no clock and no gimmick, so the card is asking you to trust the writer rather than the genre.


The premise underneath the divorce is the part worth knowing. “War” follows two rival London firms called Cathcarts and Taylor & Byrne, and each season hands them a different headline case to fight over. That is an anthology built on a fixed set of lawyers rather than a fixed story, so the people return and the lawsuit does not. Nothing in the trailer says any of this.
The omission matters more than a marketing note, because an anthology changes what a second season even means. A returning drama has to keep one story alive across years. This one has to keep a firm alive and throw a new client at it, which resets the stakes annually and puts the whole burden of continuity on the characters. That is a harder thing to sell in a hundred seconds, and the trailer does not attempt it.
Dominic West plays Morgan Henderson and Sienna Miller plays Carla Duval, and Miller gets her own billing card late in the cut. Phoebe Fox is Serena Byrne and James McArdle is Nicholas Taylor, which puts two of the surnames from the firm on the door in front of the camera. Nina Sosanya plays a figure the cast list records as Beatrice “Queen Bea” Ubosi. Pip Torrens is St John Smallwood and Archie Renaux is Jonathan “Johnny” Warren. Celia Imrie plays Budgie and Nick Mohammed plays Michael Stefanou.
The dialogue carries the rest, and this upload ships a genuine caption track instead of the auto-generated guesswork most streaming trailers arrive with. The scale claim lands early and without hedging. “This is the biggest divorce trial in British legal history.” Then the trailer states its own problem in two lines laid back to back. “We’re the better lawyers.” “They have the better case.”
That pairing is the entire show in eight words. It is a competence story rather than a justice story, because the lawyers already know they are on the wrong side of the facts and they intend to win regardless. Most legal dramas hold that admission back for a third-act crisis of conscience. This one leads with it in the trailer.

The best exchange in the cut settles the tone permanently. Somebody says they need the moral high ground and the answer comes back flat. “Oh, Nick, we’re lawyers. We need no such thing.” The cast list carries a Nicholas Taylor, which puts a name on half of that conversation, and it is the only joke in the trailer that is not made at a client’s expense.
The clients get the ugly lines instead, and the trailer hands them over without softening any of it. “She honey trapped me!” “Let’s take him for every penny he’s got. And he’s got quite a few.” “I just want to make him suffer like I did.” None of that is written to make you like anyone, and the cut never pauses on a wronged party to buy sympathy back.
The opening question gets its answer in the same stretch, and the answer is worse than the question. Somebody explains that people fall out of love and calls it the sad truth. The reply refuses it outright. “No. Why so cruel?” A third voice promises lies and betrayals, and a fourth pushes back with the line every guilty party in a courtroom eventually reaches for. “You make it sound like I’m the villain.”
There is a leak, and it is the plot engine the trailer actually shows. “We have a problem. Like, a massive problem. Someone’s been feeding information across.” The reply is the sharpest reading in the cut. “So you’d rather not have taken back the advantage?” Somebody inside one firm is passing material to the other, and the person who should be appalled is defending it.
Three more lines set up the season’s casualties. “This is a PR war, and she’s winning” says the trial is being fought in the newspapers rather than the court. “I put my career on the line for you people” says somebody will be left holding it when that fails. And a quieter one, delivered almost as an aside, draws the moral: “For people like me, the word ‘trust’ loses all meaning.” None of the three is attributed on screen and the trailer keeps it that way deliberately.
Visually it is all London and money. There is a courthouse scrum with police holding a press line back, a glass office tower lit up at night, and a phone held out with a photograph on the screen, which is the oldest evidence shot in the business. A woman walks through a bank of cameras with her head down. An establishing card over the skyline reads A NEW HBO ORIGINAL SERIES. The show is shot like a thriller rather than a procedural, which is the Kay signature the creator card promised.
The trailer closes on a small scene rather than a large one. A question. “You definitely think this is best?” An answer. “I do.” Two words that mean the opposite of what they usually mean at a wedding, delivered here about a divorce, and it is the best piece of writing in the cut.
Here is the honest read on all of it. The trailer is well made and it undersells its own show by a wide margin. An eight-episode divorce trial with a leak buried inside it is a solid season of television. Two rival firms rebuilding around a new headline case every year is a franchise, and a franchise is the thing worth following. HBO had the bigger story available and chose to lead with the smaller one. “War” premieres on 1 October.
What Do You Think? Should HBO have told the audience up front that “War” is an anthology, or does one big divorce sell it better? Is a fixed cast with a new case every season a stronger format than a continuing story? And does a creator card work on you, or do you need the premise first?
See you on the next binge!
