Sky has today released the first teaser and images for season one of WAR, the bold new Sky Original, a returning legal drama from George Kay (Lupin, Hijack), starring Dominic West and Sienna Miller, and set in the high-stakes world of two of London’s most prestigious rival law firms. Following its two-series order, production is currently underway on series two, ahead of the first series launching this October.

The eight-part series delves into the high-stakes lives of London’s most powerful lawyers as firms Cathcarts & Sons and Taylor & Byrne clash over a headline-grabbing legal battle, drawing ambitious young lawyer Jonathan “Johnny” Warren, played by Archie Renaux (Alien: Romulus, Upgraded), into a ruthless world where ambition is currency, betrayal is strategy and winning is everything.

Series one follows the explosive divorce of British tech entrepreneur Morgan Henderson (Dominic West) and international film star Carla Duval (Sienna Miller), as law firms Cathcarts & Sons and Taylor & Byrne stop at nothing to secure victory for their clients.

Also starring in series one are Phoebe Fox as Serena Byrne and James McArdle as Nicholas Taylor, partners in life and business at Taylor & Byrne; Nina Sosanya as Beatrice “Queen Bea” Ubosi and Pip Torrens as St John Smallwood, their counterparts and fierce rivals at Cathcarts & Sons, alongside Celia Imrie, Nick Mohammed, Emma Laird, Aran Murphy, Archie Panjabi, Adrian Scarborough, Shaheen Jafargholi, Akiya Henry, Honor Swinton Byrne, Miles Jupp, Kartanya Maynard, Alexandra Mardell, Dylan Murphy, Mark Quartley and Steve Furst.

WAR will premiere in the UK on 2 October on Sky and streaming service NOW.
