The Good Wife - Season 4 - Maura Tierney Joins Cast

The actress has landed a recurring role in the fourth season of the show along with British actor Marc Warren (Hustle).
Warren will play Kalinda’s (Archie Panjabi) “manipulative ex-husband, to whom she has an attraction that she finds impossible to ignore.” Tierney will play a “self-made millionaire who has become the doyenne* of Chicago Democratic politics.” Both characters will be introduced in the show’s September season premiere.
