Agatha Christie’s Tommy & Tuppence Get a Radical Modern-Day Makeover — But BritBox’s ‘First-of-Its-Kind’ Adaptation Has Already Divided Fans

Agatha Christie’s Tommy and Tuppence are about to enter unfamiliar territory.

More than a century after the detective duo first appeared in print, BritBox is bringing them into modern-day London for a new six-part series — marking the first time an English-language television adaptation has placed the characters in a contemporary setting.

The newly released trailer offers the first substantial glimpse at Tommy & Tuppence, starring The Good Doctor actress Antonia Thomas alongside Josh Dylan.

But while some viewers are excited to see Christie’s lesser-used detectives return to television, others have taken issue with the biggest change of all.

For those fans, Tommy and Tuppence belong firmly in the period in which Christie created them — and moving them into the present day risks losing much of what made the stories distinctive.

Tommy and Tuppence are coming to modern-day London

BritBox’s adaptation makes its intentions clear almost immediately.

Rather than attempting to recreate the world of Christie’s original novels, the series places its central characters against the faster, technology-driven backdrop of contemporary London.

The trailer even acknowledges modern society’s fascination with crime.

“Everyone loves a bit of crime, and these days, everyone is a detective,” a narrator observes.

It is a line that positions Tommy and Tuppence within a culture obsessed with true crime, amateur investigations and solving mysteries from behind a screen.

That approach makes the new series dramatically different from earlier adaptations.

Previous versions have generally preserved the historical atmosphere associated with Christie’s stories.

BritBox is deliberately doing something else.

Antonia Thomas and Josh Dylan become Christie’s unlikely detectives

Antonia Thomas takes on the role of Tuppence, with Josh Dylan playing Tommy.

Their personalities remain central to the partnership.

Tuppence is the more instinctive and impulsive of the two, while Tommy provides a calmer, more analytical counterweight.

The new series brings them together after a murder occurs at a party.

When someone is arrested, Tommy and Tuppence become convinced the authorities have the wrong person.

Their determination to prove the suspect’s innocence launches them into an investigation of their own.

And they will not be working entirely alone.

Imelda Staunton joins as Aunt Ada

The adaptation also features Imelda Staunton as Tommy’s aunt Ada.

The trailer suggests Ada possesses exactly the sort of experience and knowledge the inexperienced investigators may need as they attempt to unravel the mystery.

Staunton adds considerable star power to the production alongside Thomas and Dylan.

The supporting cast also includes Nicholas Richardson, Charlie Condou, Callie Cooke and Chizzy Akudolu.

But despite the recognizable names involved, much of the early conversation surrounding the series has focused not on the casting or mystery, but on its decision to relocate Christie’s characters to the 21st century.

Christie followed Tommy and Tuppence for more than 50 years

Tommy and Tuppence occupy an unusual position in Christie’s body of work.

Unlike detectives such as Hercule Poirot and Miss Marple, whose appearances largely preserve a recognizable version of themselves, Tommy and Tuppence were allowed to grow older over the course of their adventures.

Christie introduced them in The Secret Adversary in 1922.

Their story eventually stretched across five novels written over more than five decades, concluding with Postern of Fate in 1973.

Readers therefore encountered them at different stages of their lives rather than seeing them remain permanently frozen in time.

Their contrasting personalities were essential to the appeal.

Tuppence brought spontaneity and intuition.

Tommy supplied caution and evidence-based thinking.

Together, they formed a partnership built as much around their relationship as the mysteries they investigated.

Some Christie fans believe the period setting is essential

Reaction to the BritBox trailer has demonstrated how protective some readers remain of that original world.

“The charm of Tommy and Tuppence is that it’s a period piece,” one viewer argued, adding that they would “just re-read the books in protest.”

Another went further, calling the modernization “a travesty” and arguing that Christie’s original work should not be altered in this way.

Others have already declared that they will skip the series entirely.

“Nope. Not watching it,” one person wrote, claiming the adaptation did not resemble the books.

Another Christie reader compared the production unfavorably with the Joan Hickson adaptations, praising those older productions for remaining faithful to the atmosphere and style associated with Christie.

“This modernized version looks dreadful and is not true to Agatha Christie’s books at all,” the viewer wrote.

Some viewers would rather BritBox created entirely new characters

One criticism appearing among the responses goes beyond simply disliking the contemporary setting.

For some viewers, if the characters and world are going to be changed substantially, the production should become an original mystery rather than carrying Christie’s name.

“Don’t call it Agatha Christie or inspired by. Just make a new series,” one disappointed commenter argued.

That reaction captures the central challenge facing any radical modernization of a beloved literary property.

Change too little and an adaptation can feel unnecessary.

Change too much and existing fans may wonder why the original work is being adapted at all.

BritBox appears to be firmly embracing the latter risk.

The controversial change could also introduce the duo to a new audience

While traditionalists have been vocal, the trailer has not received universally negative feedback.

Other viewers have expressed excitement about the adaptation and its cast.

And the decision to move Tommy and Tuppence into the present potentially gives BritBox something different from another conventional period Christie mystery.

Rather than competing directly with decades of adaptations set against vintage country houses, drawing rooms and period costumes, the series can explore whether the core appeal of Tommy and Tuppence survives when everything surrounding them changes.

The real test will therefore be whether their personalities and chemistry remain recognizable.

If the relationship at the heart of Christie’s stories survives, the modern setting could offer a new route into the characters for viewers unfamiliar with the books.

If it does not, longtime readers may feel their early concerns were justified.

BritBox is taking a major gamble with two century-old detectives

Modernizing Christie is always likely to provoke debate.

Her stories are closely associated with a particular atmosphere, and decades of film and television adaptations have reinforced that connection.

Tommy & Tuppence is deliberately challenging it.

The new series retains Christie’s famous detective partnership but drops the pair into a world the author could never have written them into — one where practically everyone carries a camera, information travels instantly and amateur detectives have endless tools available to them.

Whether that becomes a clever reinvention or strips away too much of the original charm remains to be seen.

But weeks before audiences can judge the complete series, BritBox has already achieved one thing.

Its modern Tommy and Tuppence have people arguing about Agatha Christie all over again.

Tommy & Tuppence premieres on BritBox on September 15.
