‘Dark Knight’ viral

The “I believe in Harvey Dent” billboards were the opening salvo of one of the most interactive movie-marketing campaigns ever hatched by Hollywood: a multi-platform, hidden-in-plain-sight promotional blitz for the new Batman movie “The Dark Knight,” which stars Christian Bale and Heath Ledger and reaches theaters on July 18.

Early in the “Dark Knight” marketing campaign, an official website for the film redirected viewers to www.ibelieveinharveydent.com -- a URL notably lacking any references to Batman that urges “concerned Gotham citizens” to “take back Gotham City” by backing the candidate’s run for district attorney. And on March 12, a rally for the fictional D.A. candidate was broken up by Chicago police who seemed perplexed in the face of a group of volunteers handing out Harvey Dent bumper stickers, buttons and T-shirts.

Another website, www.ibelieveinharveydenttoo.com provides a tantalizing clue about some connection between the Joker and Two Face that will presumably be explained in the film.

But discovering it takes some work. Call up the site and you’ll see a blacked-out page with the message: “Page not found.” But pull down “select all” from your browser’s edit menu and a none too subtle shout-out to the killer clown is revealed: a pages-long sequence of repeating Ha ha ha’s. (Warner Bros.)
