Don't you see anything wrong about the fact that a god who is described as "the whitest" is being cast as a black? Your idea that a non-existent character doesn't have a race or face is patently absurd. Fictional characters have races, even if they do not possess existence. And all sense dictates that the god was white. There is a tradition of depicting the Norse gods, and they don't include blacks. Further, it's the mythos of a very white people, the Norsemen, and their description of their gods presumes that they are white. This is obvious enough that it did not have to be stated, for exactly the same reason that it is taken for granted that the mythos of a black tribe will have a racially black god (if humanoid and of a race not explicitly specified). I don't like screwing with art for the sake of minority-appeasement, and I despise this craven behaviour by the film-makers. EDIT: It appears that this is based on a comic. Note that unless the comic explicitly makes the god black through some contrived back-story, it's still appalling to make so.
