I was looking up Sasha in an interview ...
Quite disappointing that her accent's not South African
Many actors/actresses these days that make it big in Hollywood tend to get their real accents evolving into an American one - which I think is a dissapointment
It is called English. No matter where you are, America or England, it's called English
Yes, but there are different dialects, i.e. American English and British English, just like there are different dialects of Spanish -- the Spanish spoken in Spain sounds different than the Spanish spoken in Mexico or South America; there are even words in some dialects that other dialects don't use. French as well, the French spoken in France has a different dialect than French Canadian French. There is absolutely nothing incorrect in distinguishing between the English dialects -- American English and British English -- especially among linguists
