Heath Ledger's 'The Dark Knight' trailer released

Melbourne, May 5 : A new trailer of late actor Heath Ledger's last film the 'Dark Knight' has been released, giving a glimpse of his murderous anarchy in the film.

Warner Bros released the new clip, which starts off with Batman soaring through the sky 100 storeys up in Gotham City and continues with The Joker announcing his deadly intentions in dealing with his foe, reports News.com.au.

"What are you proposing?" one of his flunkies asks.

"It's simple: Kill the Batman," Ledger replies - signalling the start of his reign of anarchy.

"The city deserves a better class of criminal and I'm gonna give it to them," he adds.

The new trailer also features Aaron Eckhart, who is playing the role of Gotham district attorney Harvey Dent and becomes legendary Batman enemy Two-Face.

The Dark Night is due to release in Australia on July 17.
