Bad idea either way, casting a white guy for a black skinned race. We all know that Drow aren't meant to be black as in African, but think of the make-up job needed and how it would be compared to acting in blackface. The history of theater and film has a few too many skeletons in its closet to make that an easy pitch for a studio or an actor.
agreed - putting a white actor in black face is just begging for bad publicity. Might as well pre-book the actor, director and producer on with Rev. Al Sharpton, Oprah or Jesse Jackson to apologize & explain.
