Agatha Christie's Seven Dials (2026)

England, 1925. At a lavish country house party, a practical joke appears to have gone horribly, murderously wrong. It will be up to the unlikeliest of sleuths—the fizzingly inquisitive Lady Eileen "Bundle" Brent—to unravel a chilling plot that will change her life, cracking wide open the country house mystery.

A Lesser-Known Gem: Seven Dials is based on one of Agatha Christie's less famous novels, allowing for genuine surprises even for avid fans of her work. This means viewers can enjoy a fresh take on a classic genre without pre-conceived notions.
From Page to Screen: The series is adapted by Chris Chibnall, known for Broadchurch and Doctor Who, promising a modern sensibility while retaining the core intrigue of Christie's storytelling. His approach emphasizes momentum and character tension, steering the story away from nostalgia and toward psychological unease.
A New "It" Girl: Mia McKenna-Bruce, a BAFTA Rising Star winner, plays Lady Eileen "Bundle" Brent, described as a spirited and modern "It Girl". Bundle is portrayed as a curious and rebellious young aristocrat who refuses to be bound by the social expectations of her class.
Bonham Carter's Added Role: Helena Bonham Carter plays Lady Caterham, a character not present in the original novel. It appears Lady Caterham will take Lord Caterham's place in the story, allowing the show to explore Bundle's relationship with her mother.
Filming Locations: While the story is set in 1920s England, filming took place in Bristol and Bath, with additional scenes shot in Ronda, Spain. These locations helped replicate the period setting, with some filming occurring near recognizable spots from other Netflix series like Bridgerton.
