Mary McDonnell is a well rounded actress who has played a wide variety of roles. She will always be remembered for her performance in “Dances With Wolves”, no she is the President of the remainder of human civilization tagging along with Battlestar Galactica.
The President Roslin character is an excellent addition to the Battlestar Galactica story line, as it provides a counterpoint to Edward James Olmos’s Commander Adama. She was an insignificant cabinet member when everyone above her, including the president, were killed in the cylon attack.
Mary McDonnell plays Roslin’s initial reluctance and gradually increasing competence and self assurance as President remarkably well. Only a truly powerful performer could go toe to toe with Edward James Olmos without folding and Mary McDonnell does that in almost every episode without fail.
