I did not even recognize Jean Smart at first when watching Fargo's second season.
After having seen her comedic skills in shows like Designing Women, Frasier and Samantha Who I was somewhat surprised to see her in a serious role. Jean Smart nailed it as the matriarch of a criminal family.
There were a number of excellent performances in Fargo but Jean Smart in her understated role stood out to me. She is a real actress, not just a comedian.
