'Agatha Christie's Tommy & Tuppence' Adds 10 to Cast as Filming Kicks Off

BritBox's rise from the nichiest-niche afterthought of a streaming service to the destination for British programming has been a slow climb since it was first announced seven years ago. However, having made three successful standalone Agatha Christie miniseries in partnership with the BBC, the streaming service is now striking out on its own to resurrect one of Christie's secondary detective duos. The service announced early in 2025 that it would be taking point on a brand new adaptation of the duo known as Partners in Crime, Tommy and Tuppence Beresford, the Bright Young Things from the detective writer's early novels. Now titled Agatha Christie's Tommy & Tuppence, the new series will be a mystery of the week (or of every other week) reset in modern times.

Tommy and Tuppence don't have nearly as many novels as Jane Marple or Hercule Poirot; there are only six books and a handful of short stories, barely more than poor Superintendent Battle, who gets forcibly removed from his books whenever they get adapted. (BritBox's Murder Is Easy and Towards Zero are two of the most recent examples.) However, their high-energy hijinks and their compelling love story set them apart from Christie's other fare.

(Of course, that means the chemistry between the actors who play Tommy and Tuppence is vital to the show's success; the 2015 adaptation is an example of what happens when that chemistry doesn't work.)
