Screenwriters Brian Koppelman and David Levien (”Rounders," "Ocean's Thirteen") tell Done Deal Pro (via Bleeding Cool) that "We just finished the screenplay for our next film to direct, an adaptation of David's book ‘City Of The Sun,' and are now working on ‘National Treasure 3' for Bruckheimer".
Previously, "The Sorcerer's Apprentice" scribes Carlo Bernard and Doug Miro were attached to pen the script for a third "National Treasure". Sounds like that version has been ditched. Actor Nicolas Cage and director Jon Turteltaub are expected to return, though no word on potential dates.
'City' is based on Levien's own book about parents who hire an ex-cop with a checkered past to find their kidnapped son. They end up coming against a depraved real estate tycoon who has hands in all kinds of illegal business.
