A few months ago, I came across an article, that stated that the British Received Pronunciation accent was of recent origin.
The link to the article is below.
Yesterday i came across a Vsauce youtube video and according to the video, The General American Southern Accent is much closer to the old English accent than the British Received Pronunciation accent.
If that is the cause, shouldn't all actors in future dramas set in the Elizabethan era, the Stuart period or the English civil war should speak with a General Southern American Accent from now onwards?
Could The BBC hire American actors to play historical English characters who lived before the 18th century and simply let them use their natural American accent.
