So, you're saying that because it was filmed in America (the continents, I guess) It should star Americans (as in from all over the continents) and not only US-Americans? Because surely you didn't mean that it should mostly star US-Americans since bringing up that it was filmed on the same continent as the United States would have nothing to do with that. Do you want to imply that the cast should consist of mostly actors from all over the American continents as the show was filmed in another country than the idea originated in? Or maybe just mostly those two?
