Morgan Spector was spotted on set in Prague on September 4 as the lead of Netflix’s untitled Robert Langdon series, according to a behind‑the‑scenes photo the streamer released.

Netflix confirmed that production has begun in the Czech capital for a show based on Dan Brown’s latest novel, The Secret of Secrets. The photo shows the actor alongside co‑star Rebecca Hall, hinting at the series’ first‑look visuals.

Hall will portray scientist Katherine Solomon, while the ensemble grows with Mamoudou Athie as Michael Harris, Ben Levi Ross as Alex Conan, and Anamaria Marinca as Dr. Gessner. Richard Sammel and Elena Saurel join as Karl Muller and Susan Housemore, respectively, adding depth to the recurring cast.

The plot follows Langdon as he races to rescue a missing scientist and secure a groundbreaking manuscript that could reshape humanity’s view of the mind. The adaptation promises a mix of futuristic science and mystical lore, echoing the international intrigue that defines Brown’s books.

Series co‑creator Dan Brown serves as executive producer alongside Emma Forman and Zoe Robyn, while veteran showrunner Carlton Cuse, known for Lost and Jack Ryan, will helm writing and production duties.

Previous Langdon films starring Tom Hanks earned over $2 billion worldwide, and the novels have sold more than 250 million copies. Netflix has not announced an official title or premiere date, but the production’s progress suggests a 2025‑2026 debut.
