Netflix Starts Filming Its New Robert Langdon Series

Robert Langdon is officially back in production. Netflix has begun filming its still-untitled series in Prague, with Morgan Spector taking over the role of Dan Brown’s Harvard symbologist and Rebecca Hall starring as scientist Katherine Solomon.

The project draws from the world of Brown’s 2025 novel “The Secret of Secrets,” the sixth book centered on Langdon. Netflix marked the start of production with a first-look image of Spector and Hall on set, while also announcing five recurring additions to an already substantial ensemble.

Five more players enter the mystery

Mamoudou Athie will play Michael Harris, Ben Levi Ross has been cast as Alex Conan, and Anamaria Marinca will appear as Dr. Gessner. Richard Sammel and Elena Saurel round out the new group as Karl Muller and Susan Housemore.

They join previously announced regulars Cherry Jones as Heide Nagel, Corey Stoll as Everett Finch, Rob Delaney as Jonas Faukman and Abbey Lee as Sasha Vesna. The size of the cast suggests Netflix is building a broad conspiracy around Langdon rather than treating the adaptation as a two-character chase.

A new screen era for Langdon

The story follows Langdon as he tries to rescue a missing scientist and recover a manuscript whose discoveries could alter humanity’s understanding of the mind. The setup blends the historical puzzles associated with Brown’s hero with futuristic science and questions that reach beyond artifacts or secret societies.

Carlton Cuse, whose credits include “Lost” and “Tom Clancy’s Jack Ryan,” co-created the series with Brown and serves as writer, showrunner and executive producer. Brown is also an executive producer, keeping the novelist directly involved as the franchise moves into a new television version.

Spector inherits a role closely associated with Tom Hanks, who played Langdon in three films, while Ashley Zukerman led the 2021 television series “The Lost Symbol.” Casting Spector and Hall gives the Netflix project its own center of gravity rather than inviting a direct continuation of either earlier interpretation.

Netflix has not announced an official title or premiere date. For now, the concrete development is that cameras are rolling in Prague and the central ensemble is in place, bringing one of modern publishing’s most recognizable puzzle-solvers back toward the screen.
