I'm watching TV Guide right now and they have a long running Hollywood 411 special on Heath Ledger and they just had some guys who work on Dark Knight on there. (I don't know who, I un-muted it when I saw DK footage) I recall there being a debate awhile back on how Two Face gets scarred, (was it Joker? Maroni? Bathroom accident?), and one of the interviewees said Joker is indeed the one to toss acid at Harvey. EDIT: UPDATE: Okay it's back on, Leo Quiones is the name of the guy. I thought he worked on the movie with Heath, but apparently he's just a critic and a big Batman fan and is talking about the role of The Joker. I guess it doesn't hold as much water as I initially thought. Like I said I un-muted it halfway through the first time. Quasi-falso alarm unless he knows something we don't. Oh well!
