Anyone know why there is a black dude playing the "Whitest of Gods"?

Don't they always try to squeeze a black/latino/asian guy from time to time in their movies so people can't say they are racist or some crappy bad thinked pomegranate like that?

To be honest, I friggen hate Hollywood for this. There's always an obligatory minority or LGBT in places where there originally wasn't. I love all peoples, but stick to the friggen script! If it wasn't broken before, why you gotta go and add one in, for the sake of everyone else?
