You act like he's Denzel Washington or something....he was in a movie you liked, great.
If the other guys up for the part are as good as he is or better and "look" the part better, then I'm sorry, as I have said before it will look pretty strange to me. If not, the other guys up for the part are mediocre, then fine let the casting stand.
And just because some here are purist's does not make them racist, any more than those wanting Johnny to have blond hair in the first two movies made them haters of brown haired guys, or guys with buzz cuts...you are making a very, very, very serious judgment of people based on a few posts, knowing nothing about them at all. Those kinds of judgments really need to stop...I'm speaking of calling posters ON THIS BOARD racist because they have given a simple opinion that they would like this character to stay the race of the comics, I could really careless what someone says on another site. The other site isn't on my radar...
And no sir, comments like that ARE NOT racist, they are simply an opinion of someone that has known this character one way for decades, and simply want them to stay that way....as I said, you continue down this road of posting, there will be consequences.
