Actor Rebecca Hall has joined the Netflix series adaptation of "The Secret of Secrets", where she will essay the role of Katherine Solomon.

The series will feature the actor alongside her husband Morgan Spector, who will play the character Robert Langdon, according to the entertainment news outlet Deadline.

It is based on Dan Brown’s novel, which revolves around Harvard symbologist Robert Langdon and noetic scientist Katherine Solomon as they navigate a dangerous conspiracy in Prague involving human consciousness, a missing manuscript, and a covert CIA project.

The novel released in 2025 and is the sixth book in the Robert Langdon series by Brown.

The project “will blend futuristic science with mystical lore, delivering on the heart-pounding suspense and international intrigue that has made the Langdon stories a global phenomenon,” according to the streamer.

It is executive produced by Emma Forman of Cuse’s Genre-Arts and Zoe Robyn alongside Carlton Cuse and Brown, who also serve as co-creators and showrunners on the project.

Hall is known for her roles in projects such as "Vicky Cristina Barcelona", "Godzilla vs. Kong" and "Christine", among others.
