The adaptation will incorporate modern technology such as phones and social media, marking the first English-speaking television series to update Christie's work in this manner.
Filming is currently underway in the UK, with a premiere anticipated in 2026, starring Antonia Thomas and Josh Dylan in the title roles.
Writer and executive producer Phoebe Eclair-Powell secured permission from Christie's estate, ensuring technology enhances rather than simplifies the classic mysteries.
The characters are reimagined as an amateur sleuth duo, with Tommy as a crime writer and Tuppence as a struggling actor, aiming to attract new audiences.
