MRS. PYNCHON
She was my FAVORITE character on the series--a complex, multi-dimensional woman brought brilliantly to life.
Nancy Marchand was a GREAT actress who left us much too soon.
She has the same sort of trill to the voice that some British actresses have; the way she said certain things and her blue eyes and white hair brought to mind actress Dame Maggie Smith – though she wasn't quite old enough, and her nose was too big (Dame Maggie has very delicate features), but they do have similarity about them.
Please excuse typos/funny wording; I use speech-recognition that doesn't always recognize!
still boggles my mind that the very proper patrician Mrs. pynchon was played by the same actress who played Livia Soprano
