The eight-part series is centred around a scandal-filled divorce case between tech titan Morgan Henderson (Dominic West) and film star Carla Duval (Sienna Miller). Their case is taken on by two reputable law firms in London - Cathcarts and Taylor & Byrne - and the pair (and their respective teams) go head-to-head in the divorce case of the century. According to Sky, it's “a scandalous divorce case that sends shockwaves through boardrooms, bedrooms, and courtrooms alike.”

The official synopsis continues: “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.”

Creator and writer George Kay has teased that there's plenty of twists in store, saying: “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.”

Meghan Lyvers, Executive Director of Original Scripted, Sky, added: “The show is ambitious and provocative, brimming with unforgettable characters. It challenges the notions of power, identity, and success."

Is War worth watching?

Absolutely - with Sienna Miller and Dominic West as leads attacking each other in a win-or-lose battle, it’s set to be dramatic indeed! The actors worked together in 2005 on the West End stage adaptation of As You Like It, and have modelled jointly for Burberry campaigns - so there will no doubt be some chemistry between them, too.

For a series with a fantastic lead performance, we’d recommend Matlock, which follows Madeline Kingston (Kathy Bates), who's secretly operating under the alias at a prestigious law firm after the death of her daughter to an opioid overdose. Series 1 is available to watch on Sky and NOW. For something grittier, we'd suggest Presumed Innocent, which revolves around a Chicago prosecutor (played by Jake Gyllenhaal) who's accused of murdering his colleague and lover - but did he do it? You can watch Presumed Innocent now on Apple TV.
