What is WAR about?

Golden Globe nominated and Emmy and BAFTA Award-winning creator and showrunner George Kay (Hijack, Lupin, The Long Shadow) is bringing a bold new legal drama to Sky and NOW, WAR.

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.

George Kay, creator and writer, said: “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.”
