The Dark Knight viral web campaign is in full swing and the reveal of the full body shot of Heath Ledger as the Joker at Empire magazine has happened. What’s left. What’s the viral campaign building too.

The first assumption is a trailer. Aside from the few that attended the panel at the 2007 San Diego Comic-Con, no one has seen any footage from the film. Less that 6 months from release, that’s unbelievable for a release of this magnitude. So a trailer is a given.

What about Harvey Dent. The sites that started all of this months ago (IBelieveInHarveyDent.com and IBeliveInHarveyDentToo.com) are still there, with the content unchanged. The original WhySoSerious.com Pumpkin image decayed into a Two-Face style Jack-O-Lantern. Maybe that’s what we’re building up a too. The reveal of Two-Face. It may be in a trailer or in an image, but I feel like this build-up needs to lead to something new and unexpected. Something more than a trailer. I’d be satisfied with Two-Face.

The latest teaser for the Dark Knight (Batman 2) has appeared and it’s WhySoSerious.com. Visit the site and you see a flickering Jack-o-Lantern with a Bat Logo grin. What this all means is anyone’s guess.

WhySoSerious.com is the latest in a viral marketing campaign that started months ago to promote the film. Despite the fact that we’ve seen numerous web sites, teasers, and images; no real footage or information has been released about the film. Does the Jack-o-Lantern image mean that we’ll get to see an actual trailer on or around Halloween or does it relate to the Jeph Loeb penned Batman: The Long Halloween story, which retells Harvey Dent’s transformation into Two-Face.

More rumors are floating around that a 7-minute preview will be attached to the IMAX version of I Am Legend on Dec. 14. I hope not, because I won’t go see that film for a 7-minute preview, although many might, which is the reason it may actually happen.

Regardless, I’m eagerly awaiting whatever happens at WhySoSerious.com and in the meantime, I may have to carve a Jack-o-Lantern to match the one picture above.
