Love this teaser campaign that they just ran worldwide for the new Batman Movie , the Dark Knight. The site : http://whysoserious.com links through to a game that was played on the 28th April in various cities and resulted in 300 people (in London, possibly a lot more worldwide) getting to view a special screening of the new trailer after following a series of clues around London.

One lucky winner was given a print of the trailer that had been “scratched” by the Joker.

If you’ve ever read Frank Miller’s “Dark Knight Returns” and some of the other Batman books of the eighties then this is a really great “on-brand” approach and something the Joker would definitely have done ! Looks like Heath Ledger’s Joker will be as insane and anarchic as Millers…!
