The King T' Chaka is speaking Zulu to his son. If you want to make up a fake country and use any African dialect or a made up one sure, go ahead, but we love Marvel also and you owe it to African viewers to be authentic. If you hire a South African actor, good for you but he has to speak a Nigerian dialect or then change the name of the country he is representing. You have producers you pay for that reason! But the Hollywood idea of thinking only of American viewers who see "other languages" as gibberish is offensive to us who understand and pay money only to see have our cultures misrepresented. Hollywood has produced quite a few movies with African actors speaking different languages and pretending to be having a conversation. Yes, its acting! I know someone is going to say that!
