Netflix is reviving the Robert Langdon franchise with a new television series based on Dan Brown's sixth novel in the character's canon. The source material has demonstrated strong commercial appeal—three theatrical films generated combined revenue exceeding $1.4 billion—though critical reception remained consistently weak, with the first adaptation receiving only 25% on Rotten Tomatoes. A prior effort to adapt Langdon for streaming on Peacock, featuring Ashley Zukerman, survived merely one season before cancellation.

The upcoming eight-hour Netflix adaptation, titled 'The Secret of Secrets', will be overseen by Carlton Cuse as showrunner and creator. Morgan Spector has emerged as the leading candidate to assume the protagonist role originally portrayed by Tom Hanks on film, with Rebecca Hall in discussions to join as a supporting cast member. This production marks another attempt to translate Dan Brown's layered mystery narratives to screen, a challenge that has historically resisted resolution across both theatrical and television formats.
