Gore Verbinski (director of Pirates of the Carribbean 1-3) will be directing the videogame-turned film. What's odd about this is I remember him talking about his future after pirates and he said something like "I don't ever want to work with water again." And low and behold hes going to direct Bioshock...a movie about a sunken city at the bottom of the ocean.
It's rumored John Logan (writer of The Last Samurai and The Aviator) may write the screenplay. Recently he took Sweeney Todd from broadway and turned it into a screenplay, so he has experience in taking content and converting it to the big screen.
