Sky’s new drama War premiered on Friday, featuring Sienna Miller and Dominic West as a high-profile couple navigating a bitter divorce. The first episode received positive reviews, with some critics comparing it to the award-winning series Succession.
The eight-part anthology series follows Carla Duval, an A-list actress played by Miller, whose marriage to tech billionaire Moran Henderson—portrayed by West—falls apart after Henderson’s infidelity. The storyline unfolds as a high-stakes legal battle between two London law firms, with the divorce described as potentially the "biggest in British legal history."
Miller, who shares two young children with her fiancé Oli Green and a 14-year-old daughter with former partner Tom Sturridge, attended the London premiere with her children. Her daughter Marlowe drew attention for her resemblance to Miller, which went viral on social media.
Critics highlighted West’s portrayal of Henderson, a character who struggles to acknowledge his role in the marriage’s collapse. The series is structured as an anthology, with each season focusing on a different legal case involving the two firms, Cathcarts and Taylor & Byrne.
The premiere’s reception emphasized the sharp performances and the drama’s blend of class and trashy excess, with some reviewers noting the parallels to Miller’s own past. However, the series itself is a work of fiction, created by screenwriter George Kay, who also wrote Lupin and Killing Eve.
