Funny how some people refuse to let black actors get cast as white heroes but want them cast a black villains. You know who you are in this thread.
Anyway, Ralph Fiennes for Lex Luthor. Idris Elba for Green Lantern.
Same with Daredevil. I heard no major complaints about Micheal Clarke Duncan.
Well, to be fair, No one complained about Kingpin cause no one really gave two sh*ts about that movie :P
Anyway, I'm fine with Denzel as Lex if he can pull it off.
