Filming of Season 2 of Game of Thrones is due to move to the Croatian city of Dubrovnik next month. The tentative plans are for four weeks of filming starting on 19 September, with parts of the city standing in for King's Landing (replacing the Maltese city of Mdina) and Qarth. Winter is Coming has a more detailed report on what parts of the city are being used.
