An awesome reader named JJ sent over a link to this video earlier today which was posted on the website of 42 Entertainment, the company responsible for the ridiculously successful “Why So Serious” alternate reality game that led up to the release of last year’s highest grossing film, The Dark Knight.

It’s been over a year since the viral marketing for The Dark Knight really got cranked up. In that time, people have learned second languages, taken first steps, and gotten promotions at work. I, on the other hand, have spent most of my time following the ad campaign and avoiding showers.

It seems that every time I start to get extremely excited about another movie, such as Iron Man, something from The Dark Knight pops up to remind me that this is going to be the definitive film of Summer 2008.

I can’t believe that it has gotten to a point where there are pre-orders on a movie t-shirt, but hey The Dark Knight is a pretty big deal.

The extremely creative and intricate viral marketing campaign for Warner Brothers’ The Dark Knight took another big step forward over the past week or so.
