This has been a thread about whether a person from a particular racial background could be James Bond, but if you think about it we've ranged beyond that into age, nationality and social background - at least I've touched on class with the "can Connery really be Bond?" question from way back in 1961-62.
Thinking about it, with the possible exception of David Niven, none of the people who have played 007 on screen reflected him in terms of social class and/or nationality. Connery - Scottish certainly, but definitely not public school. Lazenby - Australian. Moore - son of a policeman, not usually the background of an upper bracket public school pupil. Dalton - Welsh born, Derbyshire raised, attended grammar school in Belper. Brosnan - proud son of Ireland. Craig - son of a publican and a teacher, from Liverpool.
None of the above were Eton/Fettes or similar in background. And it didn't matter. I dare say then that a Bond of a different nationality or racial background wouldn't matter either - provided that person could act, was suitable for the part and could play Bond convincingly. Race, social background, nationality, shouldn't be a consideration - the important point is whether the actor auditioning for the role can play the role.
Even age wasn't a consideration when Roger Moore was cast - Sean Connery stood down for a brand new Bond three years older than he was! And going back to social class the only contemporary Bond actor who comes close to Bond's school background is Toby Stephens, who played him on Radio 4 - and I'm sure he was cast only because he can act and could play Bond convincingly - and in the end, these are the only qualifications for the role that should matter.
