What do you mean?
James Bond is James Bond, still Craig, likely to not be recast as a female version (Barbara Broccoli has said as much in the past) so while it’s the oo7 role, it’s not the oo7 role as it were.
Ariel is...well, Ariel is a mermaid, and this an adaptation of an adaptation and the wars over that will burn for weeks at least, requiring all sorts of mental leaps as to why she can’t be dark skinned, or why it’s ok to recast one groups storytelling heritage and not another, and both sides will be horrifyingly right and terrifyingly wrong all at once and fight each other to the death with forks in their Hair.
Ídris? He’s too street apparently. Which frankly I always took to mean he’s too London and too working class. Though perhaps I am being too kind, and too street myself.
This oo7 business is so obviously not a recast Bond that anyone arguing for or against it on those terms is a wee bit tup, or at the very least, has too much time on their hands. Much like all of us on various forums discussing it right now. XD
Or looking for the argument...seems a few have already taken that approach on both sides. Angry people looking for the next big war for those with keyboards and touch screens to battle in.
