Meh. I'm hoping that it's either a false rumor, or like in TLH by makeup only, but have a few sections popped out by the CG. (Like in "The Mummy" where you can see through his cheek, and it's attached by a few thin strands of rotting flesh. And also no eyelid would be cool.) In color, I'd like a realistic Reddish/Pinkish, MAYBE Purple with a reasonable shade. And I gotta say, it really freaked me out and looked wierd to me before, but after thought? No hair on the burned side. And please GOD make it slightly uneven, not a straight line down his face.
....idea. You know how people were speculating that the funeral Joker crashes is Dent's? He gets acid in the face and blacks out or something, his pulse somehow goes out and they presume him dead, and they have a closed casket funeral, right? Well, Joker comes in, crashes it, but halfway through, Dent springs up screaming and weak, and gets out of the coffin much to Joker's chagrin and the crowd's surprise. Probably won't happen, but it would be SO friggin' awesome.
