Dan Brown will be very much involved in the making of big screen adaptation of his own book. The Hollywood Reporter says the author has taken over the screenwriting duty on "The Lost Symbol", which is based on his best-selling novel of the same title.
Earlier this year, Columbia Pictures hired Oscar-nominated scribe Steven Knight to pen the movie. It is not explained why Brown is chosen to rewrite the script.
Brian Grazer and John Calley are set to serve as producers for "The Lost Symbol". Ron Howard, who directed two previous films also based on Brown's novels, "The Da Vinci Code" and "Angels & Demons", has not committed to return to the follow-up project, and Tom Hanks has not signed up to reprise his role as Robert Langdon either.
In the 2009 book, which sold more than a million copies in its first day on shelves, Harvard symbologist Langdon gets mixed up with the Freemasons in Washington, D.C. The drama adventure flick is expected to come out sometime in 2012.
