LOL Long Old thread. I stopped reading at page 4, so forgive me for going back and answering lots of stuff I've read in this thread all at once. LOL
First: THANK YOU all for reposting those pics. I have spent the last 2 hours looking for this "cop in disguise" pic, because I just found out about it on another board (they pulled it before I got to see it). This is what happens when I neglect checking the Batman sites for a couple of weeks. Didn't even know they were out there.
Ok . . . I know I know . . . everyone's arguing back and forth over the perma-white, non-permawhite etc . . . I have avoided that convo everywhere, because I read something from Nolan month's ago that established what the Joker's skin would look like. . . . Wish I could remember where I read it, but like I said, it was from Nolan:
The Joker will have a grey-white face. Not bright white, but damaged or dead-looking skin.
Like I said, I wish I could remember where I read it, but I've never forgotten it. And all this time everyone's been arguing on every single Batman board I visit, and I've been kinda rolling my eyes. LOL
So anyway . . . he does add white makeup over it like we've seen in pics. But he also does have abnormal skin.
In these cop pics, it's pretty clear he has flesh-toned makeup on over it, to better blend in. Which means, his normal skin-tone has to be at least bad enough that he would stand-out if he didn't disguise it.
Ooooooh . . . I read that extra's report. It was wonderful!
I won't even tell you what I'd do to see The Joker in that pink nurses uniform!!!.
Sorry Bats! He's wearing the nurse's hat, pink uniform dress, complete with "hairy legs, the funky socks and boots". LOL

Isn't that hilarious!?!?!?
Oooh and a couple of people a few pages back were saying they hope that the Joker is really skinny. Don't worry, y'all. He's almost emaciated. Heath has gotten really thin for this role.
