Agatha Christie's Seven Dials is set to premiere on Netflix today (Thursday, 15th January), boasting a stellar line-up of British talent.
The three-part series, based on the 1929 novel The Seven Dials Mystery by the renowned crime writer, follows the adventures of young socialite Lady Bundle Brent as she investigates a prank that takes a disastrous turn following a party at her mother's residence, Chimneys.
Penned by Chris Chibnall (Broadchurch, Doctor Who) and shot across Bristol and the West Country, the captivating mystery begins with the death of a party guest under dubious circumstances and unfolds into a thrilling narrative of deceit, treachery and clandestine societies.
Not only does it draw from the work of one of the most cherished crime authors ever, but it also features an all-star cast of recognisable faces.
With the new series now ready for a weekend binge-watch, let's delve deeper into the main cast of Agatha Christie's Seven Dials and where you might have spotted them before, reports the Mirror.
Who stars in Agatha Christie's Seven Dials?
Leading the cast is up-and-coming actress Mia McKenna-Bruce, who portrays young socialite and amateur detective Lady Eileen 'Bundle' Brent.
Some viewers may recall McKenna-Bruce from her breakout role as Tee Taylor in the CBBC children's programmes Tracy Beaker Returns and The Dumping Ground. She has also starred in the films Persuasion and How to Have Sex, earning a British Independent Film Award and the BAFTA Rising Star Award for her portrayal of Tara in the latter film.
McKenna-Bruce is set to portray Maureen Starkey, the first wife of Ringo Starr, in an upcoming four-part Beatles biopic and will also feature in the comedy-thriller Everybody Wants to F*** Me, which stars Taron Egerton.
Her leading role is bolstered by a stellar line-up of British talent, including renowned stars Helena Bonham Carter as Bundle's mother, Lady Caterham, and Martin Freeman as Superintendent Battle, the detective probing the enigmatic crime.
Bonham Carter, known for her roles in iconic films such as A Room With a View, Fight Club, and the Harry Potter series, also plays the mother of another famous Netflix detective, Millie Bobby Brown's Enola Holmes.
Freeman, on the other hand, has portrayed the legendary character Bilbo Baggins in The Hobbit films and has featured in popular British TV series like The Office, Sherlock and Breeders.
The main cast also includes Edward Bluemel as the roguish bachelor Jimmy Thesiger, one of the men implicated in the prank that takes a disastrous turn. Netflix subscribers may recognise Bluemel as Sean Wiley, the brother of Emma Mackey's Maeve, from Sex Education.
He has also appeared in My Lady Jane and Killing Eve, and previously shared the screen with McKenna-Bruce in Netflix's adaptation of Persuasion.
Film and TV actor Nabhaan Rizwan also joins the cast as Foreign Office worker and party guest Ronnie Devereux. Rizwan has previously played Dionysus in the short-lived Netflix drama Kaos and starred alongside Sex Education's Aimee Lou Wood in the BBC comedy Film Club.
