Atomfall TV Show Taps Fleabag Producers to Write

3.7 million players and a BAFTA for Best British Game. That's the résumé Atomfall is carrying into its next chapter, and it's not a sequel. Rebellion announced today that its 2025 action-survival hit is being adapted into a television series, developed in partnership with UK production company Two Brothers Pictures.

The talent attached here is what makes this interesting. Harry and Jack Williams, the Two Brothers founders, will write the series. Their credits include Fleabag, The Missing, Baptiste, The Tourist, and The Assassin. Executive producing from the Two Brothers side is Alex Mercer, whose own CV includes Doctor Who and The Tourist. Rebellion co-founders Jason and Chris Kingsley will executive produce from the studio's end. According to a report from Deadline, no casting or release window has been confirmed.

For a game that launched just over a year ago, this is a remarkably strong creative team to have locked in. Most video game adaptations of this scale attach themselves to franchises with decades of built-in audience. Atomfall doesn't have that. What it does have is a setting that practically begs to be filmed: an alternate-history Lake District quarantine zone born from the real 1957 Windscale nuclear disaster, steeped in folk horror, conspiracy, and that particular brand of British unease where everyone's polite but something is very, very wrong. I've been saying for a while that Atomfall's world was more than its gameplay systems, and a TV adaptation strips out the weakest part of the equation entirely.

"Atomfall has such a distinctive British tone and setting, and it's been a real joy developing it alongside the Rebellion team," Harry and Jack Williams said. "There's something very exciting about expanding this strange, unsettling story for television." The Kingsley brothers responded in kind, noting that the Williams duo "demonstrated a clear love for Atomfall and talked about their own particular endings when they were playing the game."

What Shape Will It Take?

No details have emerged about whether the show will retell the game's story or carve out its own narrative within the quarantine zone. Given that Atomfall is a freeform survival experience where the protagonist barely speaks, I'd bet on the latter. The game's two expansions, Wicked Isle and The Red Strain, already proved there's plenty of room in this world for stories beyond the base game's main thread. British post-apocalyptic media has a history of leaning darker than its American equivalent, and the Williams brothers' track record suggests they won't shy away from that.

The Fallout comparison is unavoidable, and it cuts both ways. Amazon's Fallout show proved that a post-apocalyptic game world can translate brilliantly to television, but Fallout had 27 years of lore and millions of passionate fans before cameras ever rolled. Atomfall is working from a single game and a pair of DLC packs. Getting writers of this calibre attached early, rather than relying on name recognition alone, feels like the right call. Atomfall is available now on PC, PlayStation, and Xbox.
