Meet the Cast of Your New Favorite Period Drama, The Gilded Age

The Sex and the City-famed Cynthia Nixon takes on the role of Ada Brook, Agnes's "spinster" sister, who's at her elder sibling's mercy because she never married into money. Seemingly timid and nonconfrontational, Ada welcomes change with a warm embrace, unlike her sister. Nixon is currently starring in Sex and the City reboot And Just Like That and has appeared in a handful of movies and TV shows such as A Quiet Passion, Ratched, The Babysitters, and The Big C.
