During the 2007 Comic-Con, 42 Entertainment launched http://www.whysoserious.com/, sending fans on a scavenger hunt to unlock a teaser trailer and a new photo of the Joker. On October 31, 2007, the film's website morphed into another scavenger hunt with hidden messages, instructing fans to uncover clues at certain locations in major cities throughout the United States, and to take photographs of their discoveries. The clues combined to reveal a new photograph of the Joker and an audio clip of him from the film saying "And tonight, you're gonna break your one rule." Completing the scavenger hunt also led to another website called Rory's Death Kiss, where fans could submit photographs of themselves costumed as the Joker. Those who sent photos were mailed a copy of a fictional newspaper called The Gotham Times, whose electronic version led to the discovery of numerous other websites.
PARANORMAL ACTIVITY 2:
Paramount Picture’s Paranormal Activity 2 keeps giving us new corrupt footage, new hints, new clues with a few clips emerging on several sites in mysterious and creepy ways. Several blogs have gotten their very own viral clip from Paranormal Activity 2, the total so far being 4, but there could be more in the pipeline. Stories about how they received the footage vary as MovieFone says someone slipped it into their pants, while ComingSoon got a package at their doorstep. They've also developed the Demand it! campaign allowing the first 20 cities with the highest "demands" for the movie to be invited to attend a free screening on Wednesday, October 20th, before the film's nationwide release. To "demand" Paranormal Activity 2, fans must visit http://www.paranormalmovie.com/.
