I've heard of English-speaking countries; but English-speaking planet? my russian friends having been asking me this question all day. Suspension of disbelief is one thing , but are we supposed to believe that another planet, millions of miles away, just happens to speak american english? I don't remember there being an explanation for this, am I wrong? we could say that Krypton was at one point more than likely very similar to Earth. But even if we were to acknowledge that convergent evolution would lead to another humanoid species, the idea that superman (a kryptonian) would look like a standard handsome white dude is alittle absurd. Just look at the difference between native Africans and native East Asians. Now consider that those two groups of people are on the same planet and have for the most part the same DNA compared to other species. Even if he looked human (which itself is incredibly unlikely without some sort of external genetic intervention) he would look like some nationality or race we had never seen before. Not some white dude you would expect to model for Abercrombie and Fitch. Also, why do all kryptonians appear to be white too? in the film Thor, atleast Asgard has alot of diversity and different accents. Don't get me wrong, i loved the film. it was a great movie, i just hope they think of a cool explanation for this in MOS 2. now, the real reason is, it would not be entertaining if they spoke kryptonian in first 30 mins. i recall in the batman/superman animated movie - supergirl speaks kryptonian when batman wakes her up. https://www.youtube.com/watch?v=SJjNDrSb4QY so i just hope in the next film, they'll think of a creative way to explain why kryptonians spoke american english. if they can explain it in a way that makes sense - i'll buy it.
