Netflix has released the first teaser trailer for its upcoming three-part ‘Agatha Christie’ adaptation, ‘Seven Dials,’ offering a tantalising glimpse into a glittering yet deadly 1920s mystery. The streamer also revealed first-look images of its star-studded cast, led by Mia McKenna-Bruce, Helena Bonham Carter, Martin Freeman, Corey Mylchreest, Ed Bluemel, and Nabhaan Rizwan.
Set to premiere globally on 15 January 2026, Agatha Christie’s Seven Dials promises a witty, fast-paced, and stylish take on one of Christie’s most intriguing mysteries — where secrets, scandal, and murder lurk behind every corner of a grand English estate.
The limited series stars Mia McKenna-Bruce (How To Have Sex) as the curious and quick-witted Lady Eileen “Bundle” Brent, who finds herself at the centre of a deadly riddle. Helena Bonham Carter (One Life, Nolly) appears as the formidable Lady Caterham, while Martin Freeman (The Responder, Black Panther) plays Battle, Corey Mylchreest (Queen Charlotte) is Gerry Wade, Ed Bluemel (Killing Eve, Sex Education) is Jimmy Thesinger, and Nabhaan Rizwan (KAOS) portrays Ronnie Devereux.
Set in England, 1925, the story begins at a lavish country house party where a harmless prank takes a dark turn — and a murder follows. When the dust settles, it falls to the spirited Lady “Bundle” Brent to piece together the clues behind a chilling conspiracy that threatens to upend her world.
From Broadchurch creator Chris Chibnall, Seven Dials is written and executive produced by Chibnall, alongside Suzanne Mackie (The Crown) through her company Orchid Pictures and Chris Sussman (Good Omens). Chris Sweeney (The Tourist, Back to Life) directs and also serves as Executive Producer.
