Dominic West and Sienna Miller trade barbs in the high‑stakes divorce drama War, from a strip‑for‑cash prank to a feathered red‑carpet debut.

The new Sky Atlantic series War drops on Friday 2 October at 9 pm, pairing Dominic West with Sienna Miller in a razor-sharp eight-part legal saga. West inhabits Morgan Henderson, a socially-conscious tech billionaire whose moral compass wavers during a cruel strip-for-money game.
Miller plays Carla Duval, a narcissistic Hollywood star fighting for half of her ex’s fortune. Their on-screen animosity crackles, but underneath lies a shared history that stretches back two decades.
During a quiet moment in a London hotel, West jokes about the price he’d accept to strip down to his socks for cash.
Miller replies that she’d do it “for the lols”, prompting West to retort, “No, I’d want three figures. A hundred quid.” The line underscores the show’s central thesis: the perverse thrill that wealth can extract from ordinary people, a notion West himself sums up, “That, I suppose, is the kick billionaires must get: that people would do anything for money.”
Behind the premise: a billionaire’s dirty trick
Creator George Kay conceived the series after overhearing an ecstatic woman announce her husband finally signed divorce papers in an airport lounge. That serendipitous moment sparked an obsession with the high-stakes world of ultra-rich break-ups, where prenups, affairs, and multi-million assets collide. Kay, a self-described ’90s kid, blended the snappy repartee of Ally McBeal with the procedural gravitas of The Good Wife aiming for a drama that feels both glossy and razor-edged.
Kay admits only one scene draws directly from reality: the moment Olivia Wilde was handed custody papers at a public event, a stunt that mirrored the emotional turbulence on set. While the series is fictional, its portrayal of ruthless divorce tactics—such as the infamous strip-for-cash challenge—echoes the real-life machinations of the super-wealthy. West prepared for the role by listening to the BBC podcast Good Bad Billionaire noting that truly altruistic billionaires are scarce, “basically they’re the ones who give away all the money…”
Cast chemistry and past collaborations
West and Miller are no strangers; they first shared the stage 21 years ago in the West End production of Shakespeare’s As You Like It. Miller recalls that early rapport proved invaluable when they resumed partnership for War especially given the script’s demand for constant verbal sparring. “On the first day you’re married to someone you don’t know,” Miller says, “it’s helpful to have some sort of rapport.”
Kay wrote the role of Morgan Henderson with West in mind, having previously collaborated on the BBC’s polished drama The Hour. Miller’s Carla Duval, meanwhile, required a deliberate embrace of unlikable traits. She chose to lean into the character’s narcissism, admitting it felt uncomfortable for a natural people-pleaser. The supporting cast—Miles Jupp and Nick Mohammed as rival solicitors, Phoebe Fox as a pregnant lawyer, and Celia Imrie as a barrister—adds a comedic layer that mirrors Kay’s love for quick-witted banter.
Premiere, fashion and personal back-story
The series launched in New York with a striking red-carpet moment: Miller arrived in an Erdem creation featuring a black satin bodice and a cascade of white ostrich-feathered fabric. Paired with black heels, Charlotte Tilbury makeup, and a loose up-do, the look stole headlines, while West complemented her in a navy-blue suit. Both actors also shared personal milestones; Miller recently welcomed her third child in April, is engaged to Oli Green, and balanced filming while heavily pregnant—her maternity was woven into the storyline.
Miller’s off-screen history with invasive media adds another layer to the drama’s themes. She endured phone-hacking by the *News of the World*, testified at the Leveson Inquiry, and later settled a case with News Group Newspapers. West, too, faced brief paparazzi scrutiny in 2020 after images with Lily James emerged. Their shared experience of public scrutiny informs the series’ examination of how celebrity divorces become commodity-driven battles, where legal fees balloon and personal dignity often erodes. As Miller put it, “the more acrimonious, the more money [for the lawyers]”.
While the series promises more courtroom intrigue in a second season—rival firms now face a defamation case—the first eight episodes already deliver a potent mix of legal maneuvering, personal vendettas, and a satirical look at the billionaire class. Whether viewers are drawn by the razor-sharp dialogue, the star power of West and Miller, or the underlying critique of wealth-driven power, War stakes its claim as the season’s must-watch legal drama.
