According to Mat Reeves.
So lets see...we've had Joker, Penguin, Catwoman, Riddler, Two Face, Poison Ivy, Mr Freeze, Bane, Ras Al Gul and Scarecrow in the Batman movies. There had been rumors that Mr Freeze would appear and maybe he doesn't consider Arnolds god awful portrayal as "the real deal." That poster would suggest Two face, but I would argue Eckards performance in Dark Knight was pretty darn good. I wouldnt mind the Court of Owels and the characters that came with that storyline. And it would make sense because that one involved Damien.
