If I remember correctly, the Nazgul are all old white men in the movie.
To all those who are bitching, rest assured. I hear all of the elves in Jacksons rendition of The Hobbit are going to be black (oops, sorry, African-American, doh, did it again, Southron-Sylvanian, dammit, I mean swarthy...)
This is the dumbest issue ever. If you are offended by this film, you need to euthanize yourself.
