Rebecca Hall (“The Listeners”) is joining her husband, Morgan Spector, in the new Netflix series based on Dan Brown’s 2025 novel “The Secret of Secrets.” Hall will star as Katherine Solomon.  

Spector will star as expert symbologist Robert Langdon. The role of Langdon was first brought to screens in a trio of films starring Tom Hanks—“The Da Vinci Code,” “Angels & Demons” and “Inferno.” The Harvard professor is the subject of six books, the last of which serves as the basis for the new series. Spector previously appeared in the adaptations “The Plot Against America” and “The Mist.”

“The series will follow Langdon as he races against ancient forces—and the clock—to rescue a missing scientist and recover her groundbreaking manuscript, the contents of which could forever change humanity’s understanding of the mind,” a synopsis of the series reads.
