The Dark Knight (What to Know)

We've all been hearing about "The Dark Knight" trailer that is planned to appear in front of "I Am Legend" on December 14th. Similar to when Warner Bros. Pictures released the teaser for the film, we are all expecting for the studio to play games with us before finally unleashing the trailer.

Today, The Joker's whysoserious.com website has been updated with an animated jack-o-lantern, whose carved mouth is in the shape of the Batman symbol. Whether this is the beginning of a campaign that will eventually lead to a trailer is anyone's guess, but for now, all we have is the pumpkin.

The same jack-o-lantern has appeared in the Batman comics, including on the cover of "The Long Halloween," which delved into the origins of Two-Face. Could it mean that the treat we have been waiting for will reveal itself during Halloween? Stay tuned Batfans.
