Dominic West and Sienna Miller to Star in ‘War’ on HBO and Sky

Dominic West and Sienna Miller are set to star in the new legal thriller, War. 

The HBO and Sky Original series is set in the elite world of London law, where two rival law firms — Cathcarts and Taylor & Byrne — take on the case of the century. War “debuts with a scandalous divorce case that sends shockwaves through boardrooms, bedrooms, and courtrooms alike,” per its logline.

“Each side is certain they’ll win. But as the case spirals and loyalties fracture, reputations are on the line, and everyone’s playing to win. This is just the beginning – season one’s explosive case is the first in an anthology of headline-making legal battles,” per War‘s description. 

West will play the tech titan Morgan Henderson, while Miller portrays his estranged wife and international film star, Carla Duval. 

It also stars Phoebe Fox as Serena Byrne and James McArdle as Nicholas Taylor, partners in life and business at Taylor & Byrne; Nina Sosanya as “Her Majesty” Beatrice “Queen Bea” Ubosi, and Pip Torrens as St John Smallwood, their counterparts and fierce rivals at Cathcarts; Archie Reneaux as ambitious lawyer Jonathan “Johnny” Warren.

War has already been greenlit for a two-season commitment from HBO and Sky, following a deal brokered by Sky. Golden Globe-nominated and Emmy and BAFTA Award-winning creator and showrunner George Kay (Lupin, Hijack) created the series. 

“I am excited to be working with Sky and HBO – two homes for bold, ambitious storytelling – and our brilliant production team. War is a legal drama full of double crossing, scandal, twists, and betrayal. The kind of TV show that made me want to write TV shows,” Kay said in a statement. 

As well as Kay’s, the show’s executive producers include Willow Grylls, Matt Sandford for New Pictures, Ben Taylor, Susan Breen, Andrew Dewsbury, and Megan Spanjian for Sky.

“George Kay has created an incredibly compelling cast of characters who will have audiences rooting for them, despite the underhand tactics, dirty tricks and win at all cost mentality they bring to battle against each other in – and out – of court,” Grylls shared in a statement. 

“We are incredibly pleased to be trusted by Sky and HBO with a two series order to bring their stories to viewers around the world,” Grylls added.

Ben Taylor directed War. New Pictures (an All3Media company) and Kay’s Observatory Pictures, in association with HBO and Sky, co-produced the series.
