The Hollywood Reporter can unveil first-look images of The Crown alum Imelda Staunton as a martini-wielding Aunt Ada in the upcoming BritBox adaptation of Agatha Christie‘s Tommy & Tuppence.
Released on Monday —marking 50 years since the famed mystery novelist died —the photos show Staunton alongside co-stars Antonia Thomas (The Good Doctor, Misfits) and Josh Dylan (Buccaneers, Mamma Mia 2).
“In the first contemporary English-language television series adaptation of Agatha Christie’s stories, Tommy and Tuppence are a detective duo for the ages,” promises BritBox. “Thomas will star as Tuppence, an actress and force of nature who won’t take no for an answer. Dylan will co-star as Tommy, a meticulous, charming crime writer who has lost his passion but finds it again when whirlwind Tuppence re-enters his life.”
Staunton rounds out the trio as Ada —a wry, retired private detective and funny powerhouse who loves her great nephew, Tommy, because he never undermines her. “Only a fool would do so,” teases BritBox.

BritBox is the lead commissioner on the six-part series, produced by Lookout Point (the team behind beloved British classic Happy Valley), part of BBC Studios, and in association with Agatha Christie Limited. The program was filmed in London and will premiere on BritBox later this year.
BritBox, boasting the largest collection of Agatha Christie titles available on any streaming platform in North America, will elevate itsAgatha Christie Collection Page on Monday,refreshing it with new artwork dailyto showcase classic series and popular adaptations.
Stats shared with THR show that more than a third of BritBox viewers watched Agatha Christie BritBox Originals during their premiere week, and three of these adaptations are in the top five for the highest viewership during premiere week on the entire service. They are Agatha Christie’s Towards Zero (2025), Why Didn’t They Ask Evans? (2022), and Murder Is Easy (2023).
Tommy & Tuppence isn’t the only Christie adaptation on the horizon from the platform: Last year, BritBox and the BBC also unveiled an adaptation of Agatha Christie’sEndless Night, a three-part series produced by Mammoth Screen and Agatha Christie Limited, penned by BAFTA winner Sarah Phelps (The Sixth Commandment), her sixth Christie adaptation.

“As a lifelong Agatha fan, it was a dream come true to adapt herPartners in Crimeand bring Tommy & Tuppence’s spark into a contemporary world,” said executive producer and writer Phoebe Eclair-Powell. “Viewers can expect the high energy sleuthing, caper-ish DNA and romance of the originals, but they have been given such a new lease of life thanks to Antonia and Josh, whose chemistry and delight in the characters just makes it such a joy to watch. And then of course the cherry on top,” she adds, “Imelda Staunton lends such gravitas and wit to the character of Aunt Ada. I know she will become a firm fan favourite. It was an honour to have her at the helm of the show. I hope Agatha would approve!”
BritBox President Robert Schildhouse said that viewers have “repeatedly demonstrated” how meaningful Agatha Christie’s storytelling is to them. “We’re proud to keep her legacy alive with our premier collection of Agatha Christie titles and a longstanding commitment to presenting new Agatha Christie BritBox Originals on the service,” he said.
CEO of Agatha Christie Limited James Prichard added that at the heart of this contemporary take on Tommy & Tuppence “is my great-grandmother’s storytelling and characters. “We have been partnering with BritBox for some time, both on our new adaptations, and on our catalogue of previous shows. They are such a good home for my great-grandmother’s works,” he said.
“The stories obviously work for their existing audience, but these fresh takes also attract a new audience. Tommy & Tuppence (having a contemporary setting) is a bit different to the shows we have made before. But at its heart is my great-grandmother’s storytelling and characters, and I am sure the BritBox audience will love it.”
