The viral marketing campaign for The Dark Knight is back. This time it has shifted it’s focus to Harvey Dent. IBEelieveInHaveyDent.com has updated it’s site. It has updated all it’s info and also added a download section so you can show your support for Gotham’s leading DA. Havey has also challenged his supporters to show their support, not unlike the Joker, by emailing in video’s, pictures, and even a song, of their allegiance to not only him but the city of Gotham. It also promises to release a NEW trailer possibly as soon as this Sunday. Check it out.
