They have the ring of truth...

The Dark Knight: Teaser Trailer

Dark Knight Details Emerge

Scary Joker (Heath Ledger) looking like he may have some nasty chemical burns on his cheeks, from Chris Nolan's upcoming Batman Begins sequel, The Dark Knight.

Harvey Dent needs your vote, or so it appears from what's on the official website (or the promo site) which showcases actor Aaron Eckhart as a campaigning DA.

If you're extra crafty, you'll look in the site's source code to find this synopsis: "Batman raises the stakes in his war on crime. With the help of Lieutenant Jim Gordon and District Attorney Harvey Dent, Batman sets out to dismantle the remaining criminal organizations that plague the city streets. The partnership proves to be effective, but they soon find themselves prey to a reign of chaos unleashed by a rising criminal mastermind known to the terrified citizens of Gotham as The Joker."

Persistent rumors have Sarah Michelle Gellar joining the production, but if this is in the offing, it has yet to be officially announced.
