Re: Oh Dog, here we go again...
If the next Bond movies are set in the 50s or 60s he should definitely be a white male.
If the next Bond movies are set in present day, he can be any color or gender so long as they are British.
Sorry to the purists out there but the world has changed since Flemming's original vision/creation. If you want to remain true to original, then Bond would be dead by now or close to it. Either make a period piece or allow Bond to be updated. Welcome to a brave new world.
