Thanks to YouTube, the new The Dark Knight trailer, which is viewable "only" in theatres, has hit the web.

The poor quality video shows some nice sequences from the film and I'm sure the Warner Bros. folks aren't pleased about this leak ... but in actuality, it may give people more incentive to go to a theatre to check it out on the big screen!

The follow-up to the action hit Batman Begins, The Dark Knight reunites director Christopher Nolan and star Christian Bale, who reprises the role of Batman/Bruce Wayne. In the new film, 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.

The Dark Knight arrives in theatres on July 18.
