The viral marketing power of “The Dark Knight” has been throttled into overdrive this week as buzz-building site WhySoSerious.com [1] has influenced fans across the U.S. to play along and dress up as the Joker.

At the conclusion [2] of this week’s WhySoSerious.com challenge, which had enthusiasts roaming the streets of their cities to snap photos based on clues, a new viral marketing site was born: Rory’s Death Kiss [3].

As a reminder, Rory is the name of director Chris Nolan’s son and he has been using “Rory’s First Kiss” as the working title for the film.

RorysDeathKiss.com is asking people to dress up like the Joker and organize at the “most famous landmark in your city” (without getting arrested).

In the meantime, the Joker is either emerging as one of the most popular Halloween costumes or this specialized niche just can’t wait to replicate his evil ways.

I’ve cropped and am publishing below some of the best Joker costumes submitted to me and posted on various threads.
