Gillian Anderson is bouncing from U.K. Prime Minister to U.S. First Lady after signing up to play Eleanor Roosevelt in an upcoming anthology series.

The X-Files star, who played Margaret Thatcher on The Crown, has joined fellow 2021 Golden Globe nominees Viola Davis and Michelle Pfeiffer in The First Lady.

Aaron Cooley’s series will focus on America’s leading ladies Roosevelt, Betty Ford, and Michelle Obama.

Pfeiffer will play Ford, while Davis, who also serves as a producer for the Showtime series, will portray Obama.

Aaron Eckhart, Rhys Wakefield, and Judy Greer are attached to supporting roles.

“Gillian Anderson is an actress of incredible range and exquisite talent – she is the perfect choice to complete this powerhouse trio, who will inhabit the roles of these iconic women,” said Amy Israel, the executive vice president of scripted programming for Showtime Networks.
