'The Gilded Age' Season 3 Cast Changes: 1 Star Exits, Several Uncertain to Return, & Many Actors Will Be Back!

Christine Baranski as Agnes Van Rhijn – Expected to Return

Christine Baranski will definitely be back as Agnes Van Rhijn. Season 2 ended with Agnes losing her fortune, but her sister Ada coming in to save the day with a surprise inheritance.

Cynthia Nixon as Ada Brook – Expected to Return

Cynthia Nixon will be back as Ada Brook (aka Ada Forte). Her husband’s surprise inheritance allowed the family to keep living their comfortable lifestyle, but the power dynamics might be shifting as it now appears as if Mrs. Forte is the woman of the house, and not her sister, Mrs. Van Rhijn.
