Do You Believe in Harvey Dent?

Now this is a cool piece of movie marketing. A few days ago this image began circulating the web, along with a website: I Believe in Harvey Dent. Of course, this is an early visual from next summer's movie "The Dark Knight," which is the follow-up to "Batman Begins." That's Aaron Eckhart playing Gotham City District Attorney Harvey Dent. In the Batman universe, Dent eventually becomes the villain Two-Face but that's but that's for later.
Now, all of the sudden, another website pops up: I Believe in Harvey Dent Too. On this site the campaign poster appears to be defaced, most likely by The Joker. Watch for a few seconds and you'll notice the image begin to disappear, and the beginnings of a face being revealed. There is a place to register your e-mail address, then a code is sent to you to assist in revealing the image under the poster. Many internet movie geeks believe that as the picture disolves, we will be treated to our first image of Heath Ledger as The Joker. I gotta admit, this is a pretty fun piece of marketing, for a movie that is still a year away from release.

Update: Sunday May 20: 7:47 AM...The Joker has pretty much been revealed. Go take a look!
