Who, from the 21st century, would stand the best chance of visiting Elizabethan England and not being spotted as foreign in his manners, knowledge of day-to-day life, political knowledge, and overall demeanor?
Of course, some Shakesperean actor would probably be best suited as far as language and dress are concerned. However, I'm not convinced that Shakespeare's world of sword fights, robber princes, and moonlit balconies would prepare him well for everyday life.
