Frank Miller is one of the celebrities who got devoured by the Brain Eater around 9/11 (along with Dennis MILLER... hmm). In addition to instantly converting to a frothing, paranoid nutjob, a lot of other weird stuff like his "whore" stuff has been coming out.
There was some really weird shit with a "Batman vs Osama" comic he was trying to do, but DC kiboshed it, so he made it about some off brand Batman instead.
It's too bad because his earlier work is interesting and nuanced.
