“Let’s put a smile on that face.” Unless you’ve been living under a rock, you are well aware that the Batman Begins sequel, The Dark Knight, opens this summer starring Christian Bale as Batman and Heath Ledger as The Joker. Well, the brand-new full-length Dark Knight trailer debuted this weekend prior to Will Smith’s I Am Legend, along with a couple new movie posters (pictured on the right). WB has released the non-bootlegged, high-quality trailer, so check it out after the jump. Anyone who doubted Ledger as The Joker is now eating their words and it’ll certainly put a smile on your face.

Update: Check out the SIX-MINUTE The Dark Knight preview after the jump.

Here is the brand-new Dark Knight that is playing before I Am Legend. WB has finally released it to the net via The Joker’s viral site - so here it is in it’s perfect, non-bootlegged quality!

UPDATE: As an added bonus, here is the SIX-MINUTE PREVIEW that played prior to I Am Legend in IMAX. Not amazing quality, but hey, it’s better than a trailer right? Thanks to “tattered hoody” at YouTube for being brave enough to bootleg it. Good luck, bro.

Just in case the anything has been removed, here is another brand-new The Dark Knight poster to hold you over.
