‘Not because he’s black, but because his skills/style/etc as an actor would be a good fit for the role’
No black actor is a good fit to play James Bond anymore than than a white actor is a good fit to play Mammie on GWTW, who was also a fictional character.
I think there’s a difference between Mammie and James Bond. Yes, they are both fictional characters, and yes, as written, Mammie is black and Bond white, but I think Mammie’s race is much more central to her character (and to the story) than is Bond’s, especially given how far the Bond franchise has strayed from the source material.
That said, I understand where you are coming from as well. Just have to agree to disagree, I suppose.
