Over the years Estelle Parsons has excelled at many different kinds of acting: she won an Oscar for her role in "Bonnie and Clyde." On TV she had regular roles in both "All in the Family" and on "Roseanne" as Roseanne Barr's acerbic mother. Now she's in St Paul where she is playing Violet Weston, the wasp-tongued, pill-popping matriarch of a dysfunctional family in the awardwinning play "August, Osage County."
