Joining India on the location list for Bond 23 appears to be Istanbul, which provided much of the atmosphere for From Russia With Love and made a brief appearance in Tomorrow Never Dies. An article in the Turkish Hurriyet Daily News states:
Secret agent 007 is coming to Istanbul. James Bond, one of Hollywood’s most enduring characters, will have new adventures in the city’s historical neighborhood Sultanahmet in the next film in the series. Director Sam Mendes has received permission from Turkish Culture Minister Ertuğrul Günay to shoot scenes for the film in Sultanahmet Square.
The prospect of a shoot in Turkey appeals much more than the Bolivian desert from the previous film. While it is hardly unexplored for 007, Turkey has a rich culture that should lend the film some real visual character.
