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.
