I have been following the Joker's website since last year. WhySoSerious.com is one of the promotional viral websites for the upcoming Dark Knight movie and it has been a lot of fun checking it for updates. If you visit the site, click on the hidden links that you find within the newspaper printed letters, to uncover another website filled with pictures of all different jokers all over the country.
Maybe all these photos were taken at the places that were hinted upon during the last site update, which seemed to give clues to find something at different locations all over the country.
The Dark Knight hits theaters on July 19, 2008 - and you can prepare to go to the movie in style with the Batman movie costumes available for adults and children at AnniesCostumes.com.
