At last, Dan Brown’s ‘The Secret of Secrets’ arrives on Netflix
Netflix is lining up Dan Brown’s latest mystery, sending Robert Langdon into a globe-trotting puzzle where symbols, secrets, and danger stack up fast.
Street closures and crew notices are popping up around Prague’s Old Town as Netflix ’s take on Dan Brown’s latest Robert Langdon thriller readies its first shots. According to The Prague Reporter, production prep is underway now, with earlier location filings pointing to a Prague shoot running from late August 2026 through March 2027. The series is also slated to film in New York City, keeping the globetrotting vibe that’s part of the franchise ’s DNA.
Morgan Spector is stepping into the tweed as Harvard symbologist Robert Langdon, with Carlton Cuse (Lost, Locke & Key) serving as showrunner and co-creating the series with Brown. Netflix has confirmed Rebecca Hall as Katherine Solomon, the scientist at the heart of the mystery.
Who’s in it

- Rebecca Hall — Katherine Solomon
- Cherry Jones

- Rob Delaney
- Abbey Lee
In The Secret of Secrets, Langdon arrives in Prague to attend a lecture by Katherine, a prominent noetic scientist he’s recently begun dating. Her forthcoming book hints at game‑changing discoveries about human consciousness. Then everything goes sideways: Katherine vanishes, her manuscript is gone, and Langdon becomes the target of a widening chase.
The hunt spills beyond Prague to London and New York, blending near‑future science with mystical lore and the Czech capital’s dense web of history and myth. Netflix has framed the story as an evolution for Langdon, in part because Katherine is his first truly serious love interest onscreen.
Production is expected to run in Prague from late August 2026 through March 2027.
Cuse has said Brown’s puzzle‑box plotting breathes better over an eight‑hour season than it ever could in a two‑hour movie, which should give the adaptation room for its codes, clues and big ideas.
There’s no Netflix premiere date yet. With filming slated through March 2027, reporting suggests a late‑2027 debut is possible, though 2028 is the more realistic window.
