Tommy & Tuppence reveals first look images
The Hollywood Reporter has released first-look images of BritBox’s upcoming adaptation of Agatha Christie’s Tommy & Tuppence, marking 50 years since the author’s death. Imelda Staunton appears as Aunt Ada, a retired detective and great-aunt to Tommy. She stars alongside Antonia Thomas as Tuppence and Josh Dylan as Tommy in what BritBox describes as “a detective duo for the ages.”
BritBox confirmed this marks the first contemporary English-language TV adaptation of Agatha Christie’s stories. Thomas plays Tuppence, “an actress and force of nature.” Dylan plays Tommy, “a meticulous, charming crime writer” who reconnects with Tuppence and rediscovers his passion for crime-solving. Staunton’s Aunt Ada is described as “a wry, retired private detective and funny powerhouse who loves her great nephew, Tommy, because he never undermines her.”
Lookout Point produced the six-part series in association with Agatha Christie Limited. The team filmed it in London and plans to premiere it later in 2026. Executive producer and writer Phoebe Eclair-Powell said, “As a lifelong Agatha fan, it was a dream come true to adapt her Partners in Crime and bring Tommy & Tuppence’s spark into a contemporary world.”
BritBox offers the largest collection of Agatha Christie titles on any North American streaming platform. Data shared with The Hollywood Reporter shows that over a third of BritBox viewers watched new Agatha Christie Originals during their premiere week. Titles such as Towards Zero (2025), Why Didn’t They Ask Evans? (2022), and Murder Is Easy (2023) rank among the platform’s top five most-viewed premieres.
James Prichard, CEO of Agatha Christie Limited, said the show “is a bit different” from earlier adaptations. However, he added, “at its heart is my great-grandmother’s storytelling and characters.”
