A footage from the movie was screened exclusively at Wizard World Chicago with lots of shots on The Joker.
Appeared at Wizard World Chicago as expected before, the cast and crew of "The Dark Knight" really brought huge delight to those in attendance as they not only took questions thrown at them but also, most importantly, screened a special "sizzle reel" cut from the project, of which production was said by helmer Christopher Nolan to be exactly 50 percent done.
Only being shown for the fans to see it once, the footage featured number of shots of primary villain in the flick, The Joker, in majority, while also introducing District Attorney Harvey Dent as well as the new Rachel Dawes to the viewers.
Other cuts reportedly presented a war-torn Gotham City and Bruce Wayne testing out new gear and working on equipment plus his alter ego, our hero Batman, in his new suit while riding the Batpod. Most notable one was the shot which confirms Dent transformation as the evil Two Face when someone coming up to the District Attorney saying, "I thought you were dead?" which is replied short by the man, "Half", before a massive scarring spotted on the left side of his face.
More detailed description on the footage can be read at Wizard Universe, which has also posted the full Q&A with cast and crew of the flick during the presentation.
