Netflix has released the first teaser trailer for Agatha Christie’s Seven Dials, a gripping three-part adaptation of the Queen’s 1929 novel The Seven Dials Mystery, set to premiere on January 15, 2026. The series follows Bundle Brent, a spirited young aristocrat (played by Mia McKenna-Bruce), as she dives into a web of intrigue after a weekend house party at a sprawling English estate spirals into chaos with a shocking death. Directed by Chris Sweeney (The Tourist) and written by Broadchurch creator Chris Chibnall, the production promises a blend of witty banter, opulent 1920s visuals, and Christie’s signature twists, executive produced by The Crown‘s Suzanne Mackie through her Orchid Pictures banner.

The trailer, unveiled on November 4, 2025, during a virtual event hosted by Netflix Tudum, opens with sweeping shots of Chimneys Manor—a fictional pile of ivy-covered stone and manicured gardens—bustling with jazz-age revelers in flapper gowns and tuxedos. Laughter echoes over champagne flutes until a gunshot shatters the idyll, leaving guests frozen amid shattered crystal. Helena Bonham Carter, as the enigmatic Lady Eileen “Bundle” Brent’s aunt, delivers the line that hooks: “People who go looking for trouble usually find it.” Martin Freeman joins as the suave yet suspicious Sir Oswald Coote, while a seven-faced clock ticks ominously, symbolizing the novel’s central enigma. McKenna-Bruce’s Bundle, sharp-eyed and unyielding, emerges as the unlikely detective, quipping, “Murder doesn’t respect the guest list.”

Chibnall’s script modernizes the tale without losing its Roaring Twenties flavor, emphasizing Bundle’s agency in a male-dominated world. “Bundle is one of my great-grandmother’s most vibrant young women—humorous, clever, and fearless,” said James Prichard, Agatha Christie’s great-grandson and executive producer via Agatha Christie Limited. The story, originally a standalone sequel to The Secret of Chimneys (1925), weaves espionage, jealousy, and hidden motives among a cast of colorful suspects, including a foreign diplomat and a motorcycle enthusiast. Filming wrapped in Yorkshire and London studios last spring, with period details from costume house Cosprop (The Favourite) ensuring authenticity—think pearl necklaces, cigarette holders, and a fleet of vintage Bentleys.

The ensemble boasts British talent: Bonham Carter channels eccentric poise, Freeman adds dry wit, and supporting roles go to Orla Fitzgerald as a scheming socialite, Tom Goodman-Hill as a bumbling inspector, and newcomer Arta Dubrovska as a enigmatic guest. Sweeney, known for taut pacing, directs all episodes, with cinematographer Suzie Lavelle (The Crown) capturing the manor’s gothic grandeur. Chibnall, drawing from his Doctor Who tenure, infuses subtle nods to Christie’s life—her 1926 disappearance after a marital scandal mirrors Bundle’s quest for buried truths.

This marks Netflix’s third Christie collaboration under a 2021 deal with Agatha Christie Limited, following The Pale Horse (2020) and Why Didn’t They Ask Evans? (2022). Orchid Pictures’ involvement signals Mackie’s vision for elevated mysteries; she called it “a witty, epic drama for a new generation.” Prichard echoed, “Viewers will love this world—and hope for more,” hinting at spin-offs featuring Bundle, a character Christie fans have long championed.

The trailer’s drop coincided with a 40% spike in streams of Christie’s audiobooks on Audible, per company data, and #SevenDials trended globally with 800,000 posts. Fan reactions blend excitement and speculation: TikTok theories posit a clock as the murder weapon, while Reddit dissected casting—”Bonham Carter as the red herring aunt? Genius.” Critics’ early buzz from Tudum previews praises the “lavish yet lean” production, with Variety noting, “It recaptures Christie’s playful peril without overindulging.”

Production notes highlight sustainability: sets used recycled fabrics, and electric vehicles doubled for period cars in non-driving scenes. The score, by Debbie Wiseman (Wolf Hall), mixes orchestral swells with 1920s jazz riffs, teasing a soundtrack drop in December. Netflix’s global rollout includes dubs in 15 languages, targeting Christie’s 2 billion book sales legacy.

As January approaches, Seven Dials positions Netflix against BBC’s Death on the Nile remake (slated for 2026) and Acorn TV’s Poirot specials. For McKenna-Bruce, post-Vampire Academy, it’s a breakout: “Bundle’s my dream role—smart, sassy, solving crimes in stilettos.” Bonham Carter, fresh from The Crown Season 6, adds, “Agatha’s worlds are addictive—elegant on top, deadly underneath.”

The series arrives amid Christie’s centennial (her first novel turned 100 in 2020), with tie-ins like a Chimneys-inspired escape room at Netflix House in London. Prichard envisions more: “Bundle deserves her own adventures.” For now, the trailer—clocking 2 million views in 24 hours—whets appetites for a winter whodunit.

In Christie’s tradition, Seven Dials reminds: beneath the glamour, secrets tick away. Mark January 15—Bundle’s waiting to wind them up.
