art of the fun of The Dark Knight’s advertising campaign has been watching how gradually information has been released to the public. Sure, as with any Hollywood movie, the cast was general knowledge before the cameras started rolling. But once production began the publicity department has been very careful about the information they leak out. In the age of the internet, rabid fans will constantly discuss and debate any upcoming film, particularly one as geek-centric as a Batman movie. Left unchecked, footage will be stolen and stills will be taken from the set without permission. Information will get to the fans. It’s just a matter of how and when.

There was one Dark Knight secret that the fans have known since the beginning: the fact that Two Face will be appearing in the movie.

The people behind The Dark Knight have been conscious about this from the beginning and orchestrated an incredibly precise and organized internet advertising campaign that has been giving out information faster than any fanboy could upload a blurry cell phone camera pic. A full year ago, the first Dark Knight website appeared, giving the world a peak at Heath Ledger’s unique version of the Joker. Since then, the studio has been ladling out information, footage, and photos to fans, who have been hungrily following along like children following a trail of breadcrumbs in the forest. The studio has been very careful about what they’ve shown and played their hands pretty close to their chests. But there was one secret that the fans have known since the beginning: the fact that Two Face will be appearing in the movie.
