The promotional machine for Christopher Nolan’s The Dark Knight continues to ramp up. As you may have noticed below, I’ve been posting several additional new photos of Heath Ledger’s Joker to the entry of a few days ago. Also, the online viral marketing has continued apace: First an edition of the Gotham Times was released, and, in keeping with the Dark Detective meme, that’s led to all kinds of spinoff sister sites and more municipal tangents than The Wire (Gotham Police Dept. (and Internal Affairs), Gotham National Bank, Gotham School District, Gotham’s DA hotline, Gotham City Rail, Gotham Cab, Acme Security Systems, Gotham Victim Advocate Organization, Remembering Gina, and a Jokerized version of the paper.) Whatsmore, at the original viral Joker site, you can now take a personality profile or try to open a vault for further clues. (Set your clock for 7:38am to do so.) Finally, both the trailer and the first seven minutes of the film will be released on December 14, before the IMAX version of Will Smith’s Omega Man-update I Am Legend. To the IMAXcave, Robin! Update: Another countdown, set for noon on Tuesday. The trailer, perhaps? Update 2: Nope. After some shenanigans involving local bakeries (the NYC ones were over in Yorktown), it’s a new one-sheet.
