Dominic West and Sienna Miller premiered War, George Kay’s legal drama for Sky and HBO about two London law firms fighting a film star’s divorce.
Dominic West and Sienna Miller led the world premiere of War at Odeon Luxe Leicester Square in the West End on Wednesday 16 September 2026. Sky made the legal drama with HBO, and its creator, George Kay, walked the carpet with them.
West plays the technology mogul Morgan Henderson. Born in Sheffield in 1969, he was educated at Eton and trained at the Guildhall School of Music and Drama. Detective Jimmy McNulty in The Wire made his name, and he later played the Prince of Wales in The Crown.
Miller plays Henderson’s wife, the film star Carla Duval. Kay co-created the Netflix series Lupin and the Apple TV thriller Hijack.
The eight-part first series follows two London firms, Cathcarts and Taylor and Byrne, on opposite sides of the couple’s divorce. Ben Taylor directs, and Phoebe Fox, James McArdle, Nina Sosanya and Pip Torrens complete the leading cast.
The premiere came ahead of the series’ debut on HBO on 1 October and on Sky Atlantic a day later. Sky and HBO ordered two series as an anthology. The second, a defamation case with Marisa Tomei, Kelly Macdonald and David Harewood, began production in 2026.
Emma Laird was among the guests.
