I can understand white British Actors being sort after in Hollywood to do the British accent in Romance or epic movies with British or European setting. What I don't understand is why most Black Actors of African origin are of British Nationality. Why are they sort after. It's not like they do the British accent in most of their movies. They're mostly called upon to act as a typical Africa American. Why not those with American background. What's special about the African Brits? Most of them were either born or have lived in Britain. The likes of Ejiofor, Oyelowo, Chikezie, Alozie, Idris Elba etc.

acting is not just about accent, its about looks and also marketability...they have wider appeal on both continents or even more considering their varied background..they are not typecasted yet hence not rinsed out

and most importantly they can act!
