Director
Christopher Nolan has said that this portrayal will be inspired by
The Killing Joke, and the character's first two appearances in the comics

I believe this is what he is referring too. Now I'm all for page to screen changes that are reasonable and make sense. But if Joker's natural look is canned in favor of some artsy villian that looks more like Clockwork Orange than his source material, and has makeup that looks like a 4yr old's attempt, than I'm gonna be a TAD dissapointed.
