Agatha Christie's most charming crime-solving duo is making a long-awaited comeback. BritBox has dropped the first trailer for its upcoming miniseries Tommy & Tuppence, giving fans a fresh look at the beloved private detectives reimagined for a modern audience. The six-episode series stars Josh Dylan and Antonia Thomas as the titular pair, and it's set to premiere on September 15, 2026, in the U.S. and Canada.
The trailer promises a lively, chaotic mystery show that balances humor with suspense. Unlike traditional Christie adaptations, this version leans into a more playful tone, following the young couple as they navigate their relationship—falling in love, breaking up, and reuniting—all while tackling a series of intriguing cases. It's a fresh take that feels both nostalgic and contemporary.
A Modern Twist on a Classic Pair
For those unfamiliar, Tommy Beresford and Prudence "Tuppence" Cowley first appeared in Christie's 1922 novel The Secret Adversary. They've been adapted several times over the decades, but this new series marks the first time they've been updated to the present day. The shift in setting allows the show to explore modern mysteries while retaining the wit and charm of the original characters.
Josh Dylan, known for his roles in Mamma Mia! Here We Go Again and The Last Vermeer, brings a roguish energy to Tommy. Antonia Thomas, who starred in The Good Doctor and Misfits, infuses Tuppence with intelligence and sass. Their on-screen chemistry is electric, as seen in the trailer, and it's clear the show will lean heavily on their dynamic.

What to Expect from the Series
While plot details remain under wraps, the trailer hints at a mix of standalone cases and an overarching mystery. The showrunner has described it as a "romp through the world of crime-solving," with each episode bringing a new puzzle for the duo to unravel. The tone is lighter than typical Christie fare, drawing comparisons to shows like Only Murders in the Building or Psych.
BritBox has been expanding its original programming, and this series is a major addition. The streaming service, known for its library of British classics, is betting big on this modern take. For fans of the genre, it's a must-watch. And if you're looking for more British mystery content, don't miss Criminal Record: Apple TV's Gripping British Mystery Reaches 100-Day Streaming Milestone.
