Produced by Lookout Point in association with Agatha Christie Limited, the first English-language, contemporary Agatha Christie television adaptation begins shooting this Fall

BritBox have announced that Antonia Thomas (The Good Doctor, Still Up), Josh Dylan (Buccaneers, Mamma Mia 2), and Imelda Staunton (Harry Potter, the Paddington films) will star in Agatha Christie’s Tommy & Tuppence, a six-part contemporary adaptation of the Agatha Christie novels and short stories. BritBox is the lead commissioner on the series, which will be produced by Lookout Point (Pride and Prejudice, Happy Valley), part of BBC Studios, in association with Agatha Christie Limited. The series will begin shooting this fall.


In the first contemporary English language television series adaptation of Agatha Christie’s stories, Tommy and Tuppence are a detective duo for the ages. They fall in love, fall out of it, and tumble back in, all while solving some thrilling, entertaining mysteries along the way.

 

Thomas will star as Tuppence, an actress and force of nature who won’t take no for an answer. Dylan will co-star as Tommy, a meticulous, charming crime writer who has lost his passion but finds it again when whirlwind Tuppence re-enters his life. Staunton rounds out the trio as the formidable Aunt Ada, a wry, retired private detective who loves her nephew, Tommy, because he never undermines her - only a fool would do so.

 

The series is written by Phoebe Eclair-Powell (The Road Trip, Harm), who also executive produces, in her first drama series commission for television. Fergus O’Brien (Happy Valley, The Tourist) will direct the first four episodes and Ellie Heydon (Outrageous, Trying) the last two. Stella Merz (Miss Austen, Gentleman Jack) will produce.
