Morgan Spector is in negotiations to play Professor Robert Langdon in Netflix’s upcoming series adaptation of Dan Brown’s latest novel, The Secret of Secrets. Rebecca Hall is also in talks to join the project as the female lead, Katherine Solomon.
According to Deadline, the series will adapt Brown’s newest Robert Langdon novel and reunite audiences with the renowned symbologist, previously portrayed by Tom Hanks in the film franchise. Netflix declined to comment on the reported casting.
If finalised, Spector will play Langdon as he races against time and ancient forces to rescue his missing girlfriend, scientist Katherine Solomon, and recover her groundbreaking manuscript, whose discoveries could permanently change humanity’s understanding of the human mind. Hall is in negotiations to portray Katherine Solomon.
Sources said the project will not affect Spector’s role as George Russell in HBO’s The Gilded Age. He is expected to continue with both productions if the period drama receives a fifth-season renewal. The fourth season is expected to premiere this autumn.
The adaptation marks the first television acting collaboration between real-life couple Spector and Hall. The pair have previously appeared together in stage productions and films, including the Broadway revival of Machinal, Christine and Permission.
Dan Brown and Carlton Cuse serve as co-creators and executive producers of the series, with Cuse also writing and serving as showrunner. Emma Forman executive produces through Cuse’s Genre-Arts banner. Netflix ordered the project straight to series after acquiring it in May 2025. Filming is scheduled to begin this autumn in Prague, where the novel is set.
Published by Doubleday in September, The Secret of Secrets is the sixth novel in Brown’s Robert Langdon series, following Angels & Demons (2000), The Da Vinci Code (2003), The Lost Symbol (2009), Inferno (2013) and Origin (2017). Brown’s novels have sold more than 250 million copies in 56 languages.
Three of the books were adapted into feature films starring Tom Hanks and directed by Ron Howard. The Da Vinci Code (2006), Angels & Demons (2009) and Inferno (2016) have earned a combined worldwide box office of $2.24 billion in inflation-adjusted 2025 dollars. The Lost Symbol was adapted into a Peacock television series in 2021, with Ashley Zukerman portraying a younger Langdon. The series ran for one season.
The project would also mark Spector’s return to Netflix following his recent recurring role in Black Rabbit, while Hall most recently appeared in Ryan Murphy’s FX series The Beauty.
