Marisa Tomei, Kelly Macdonald & David Harewood Join Explosive Season 2 of HBO/Sky Legal Drama ‘War'

All-Star Lineup Gears Up for Second Round of Courtroom Battles

Get ready for a whole new war. HBO and Sky's upcoming legal drama War is stacking its second season with an absolutely stunning ensemble, headlined by Oscar winner Marisa Tomei, BAFTA winner Kelly Macdonald, and powerhouse actor David Harewood. According to the details captured in Screenshot (550).png, production on Season 2 is about to begin — and the case this time is a defamation explosion that promises to be as vicious as it is headline-grabbing.

What’s the Verdict on Season 1?

Before we dive into the new blood, let’s set the docket. Season 1 of War, which wrapped filming in February and is set to premiere later this year, stars Dominic West and Sienna Miller as a high-net-worth divorcing couple. Think money, power, and the kind of intimate warfare that only a divorce lawyer could love. But Season 2 flips the script entirely: a defamation case so incendiary it could make the whole city take sides.

Creator George Kay — the mastermind behind Hijack and Lupin — is back as lead writer, and he’s bringing a fresh battalion of legal warriors to the fray.

Meet the New Recruits

Marisa Tomei — The Oscar-Winning Heavy Hitter

Few actors can turn a courtroom into a stage like Marisa Tomei. Ever since her iconic, scene-stealing turn in My Cousin Vinny (which earned her an Academy Award), Tomei has been a magnet for complex, fiercely intelligent characters. From The Wrestler to Spider-Man: No Way Home, she brings raw emotional depth and whip-smart energy. In War, she’s stepping into a role that’s sure to leverage that trademark intensity.

Kelly Macdonald — Subtle Fire, Quiet Power

Scottish-born Kelly Macdonald has made a career of playing women with hidden depths. Her breakout in Trainspotting led to a BAFTA for The Girl in the Café and a Golden Globe nomination for Boardwalk Empire. She’s also the voice of Merida in Brave. Macdonald’s ability to convey simmering emotion with a single glance makes her a perfect fit for the high-stakes world of defamation litigation.

David Harewood — Commanding Presence

David Harewood is no stranger to power struggles. Whether as David Estes in Homeland or Martian Manhunter in Supergirl, he radiates authority and vulnerability in equal measure. His addition to War signals that the drama will be as much about personal stakes as legal strategy.

Full Cast Breakdown — More Than a Handful of Stars

The roster in Screenshot (550).png reads like a who’s who of British and international talent. Alongside Tomei, Macdonald, and Harewood, the new season features:

• Claire Skinner — beloved for Outnumbered and Bridgerton
• Omari Douglas — breakout star of It’s a Sin
• Kadiff Kirwan — from Fleabag and Chewing Gum
• Douglas Booth — known for The Great and Romeo & Juliet
• Charles Edwards — The Crown and Downton Abbey veteran
• Luca Pasqualino — Italian star of My Brilliant Friend
• Rebecca Front — comedy legend from The Thick of It
• Alexandra Maria Lara — international film star (Downfall)
• Linus Roache — Law & Order and Vikings alum
• Violet Braeckman, Sasha Behar, Sid Phoenix, Cornelius Booth, Megan Channell

These are not just names — they’re actors who can turn a line of dialogue into a knife fight.

The Returning Regulars — The Firm vs. The Firm

The core structure of War pits two rival London law firms against each other. Phoebe Fox and James McArdle return as partners in life and business at Taylor & Byrne, while Nina Sosanya and Pip Torrens reprise their roles as their adversaries at Cathcarts. That’s the kind of dramatic friction that makes legal thrillers addictive.

Also back is Archie Renaux (Shadow and Bone) as ambitious associate Jonathan “Johnny” Warren. Plus, the first season already includes Emma Laird, Nick Mohammed, Akiya Henry, Honor Swinton Byrne, Miles Jupp, Kartanya Maynard, Alexandra Mardell, and Steve Furst. This is an embarrassment of riches.

Who’s Running the Show?

George Kay leads the writing team, with Kelly Jones, Jess Brittain, Catherine Shepherd, Yemi Oyefuwa, and Krissie Ducker contributing scripts. Directing the new season is Ben Taylor, best known for his work on Sex Education — so expect that same balance of sharp dialogue and emotional intimacy.

Executive producers include Willow O’Sullivan and Imogen O’Sullivan for New Pictures, along with Ben Taylor, Susan Breen, and Megan Spanjian for Sky. Matt Carver serves as series producer. The show is a co-production between New Pictures (an All3Media company), Observatory Pictures, in association with Sky and HBO.

Why ‘War’ Could Be the Next Must-Watch Legal Drama

With a premise that taps into the most corrosive public battles — divorce, defamation, corporate greed — War feels like it’s built for the streaming era. SEO keywords like “HBO legal drama 2026”, “Marisa Tomei TV show”, “Kelly Macdonald Sky series” will be buzzing after this announcement.

And the timing is perfect. As Season 1 prepares to launch, the casting news for Season 2 ensures the hype train is already rolling. Fans of Suits, The Good Wife, or Better Call Saul — take note. This one has the firepower to be the next big courtroom obsession.

Stay tuned for more updates as production gets underway. The war is far from over.
