Though a month is still left before the release of Angels & Demons, the second film adaptation of Dan Brown’s works, Sony Pictures is already moving forward with the third.

Brown earlier announced that “The Lost Symbol”, his third book featuring the character of Robert Langdon, will hit bookstores on September 15.

As a result, Sony is moving forward with its plan to adapt the property and is certain to get director Ron Howard and star Tom Hanks to reprise their roles.

Details of the book are unknown at the moment, but it has been revealed that it takes place over a twelve-hour period.
