The official IMAX site has posted a video clip for The Dark Knight’s IMAX prologue featurette, which includes interview footage with director Christopher Nolan.

Also, the film’s viral marketing campaign is in full force, with a new site going live today at http://www.thegothamtimes.com. If you click around on page 1, you’ll unveil a message from The Joker. This leads to www.thehahahatimes.com, which is the online version of the newspapers that were sent to the rorysdeathkiss.com winners.

From the Ha Ha Ha Times page, you can get to other viral sites:

www.gothamnationalbank.com
www.rememberinggina.org
www.gothampolice.com
www.wearetheanswer.org
www.gothamcityrail.com

Lastly, the Why So Serious? site has been updated to include a Personality Profile. The personality quiz contains 14 questions, which determine which of nine personalities you have. A message is then displayed advising that “your next test will occur in a few days, so keep your eyes open and a smile on your face.”
