Unfortunately though, this too was canceled. The TV show saw Langdon investigating the actions of the Freemasons and searching for his abducted friend and mentor (Eddie Izzard), had middling to positive reviews (far better than the movies fared critically).

However, those abandoned placs weren't scrapped entirely, and The Lost Symbol eventually making its way into a TV format, with some major changes, including moving its appearance in the timeline to be a prequel to Da Vinci Code, including recasting Robert Langdon with a younger Ashley Zuckerman ( Succession, Fear Street).

Director Ron Howard and star Tom Hanks abandoned that plan, stating that the material went over too much of the same ground as The Da Vinci Code and Angels and Demons, and opted to adapt the newer book in the franchise. While plans for a fourth Robert Langdon movie currently appear not to be on the cards, the original plans for the third installment, Inferno, were to adapt an entirely different Dan Brown book – The Lost Symbol. That said, there was a noticeable downturn in profit with each entry. None of The Da Vinci Code series of Robert Langdon centered films and TV show have received spectacular reviews by critics, but they've mostly been hits.
