Genie:
Good point, hpwever, not the one I was hoping to make.
In those movies, the different populations were made to speak
as they did purposely to facilitate the audience's perception
of specific groups.

In attempting to elucidate the origins of stage Yiddish, I was
hoping to try and get you to picture, let's say, three brothers
(raised in the same home, etc.) being portrayed by actors with
wildly different dialects.

Peace,
