Batman pulls a hat trick in "The Dark Knight." According to FilmIck, previously-reported castmember Aaron Eckhart is going to be pulling double-duty after all.  District Attorney Harvey Dent (Eckhart) is getting his famous makeover before the end of the movie, despite earlier claims from the production crew that this wouldn't be the case.  There's even a description of the new look:

"Scarring across the nose just a tad bit. One of his eye is deformed.

And little bubbles across the scarring (They're manips that look similar). Wicked cool."

The going theory is that Dent is getting scarred near the end of the film in order to set up things for the third flick.

Meanwhile, Anthony Michael Hall is getting into a familiar costume as well.  There's an enigmatic comment on Batman On Film and a clearer one on FilmIck, putting an end to the question mark behind his top secret character's identity.
