The problem with Idris Elba is that it becomes the whole 'first black bond' thing and he's quoted as saying he would hate that, this was when they approached him a few years ago when it looked like Daniel Craig wanted out of the whole franchise. You just know the media would have a field day with that story too, as if it was inconceivable. Sure, in the original books he was the rich orphan white kid from the all boys boarding school but it's sad we can't just have him be a black guy.
Anyway, I do desperately want to see Idris Elba in a solid spy flick or thriller type movie. I think he would be awesome.
