Gillian Anderson is sharing a first look at an anticipated new role.

On Thursday, the former “X-Files” star posted a photo on Twitter in which she is being fitted for a wig for her role as Eleanor Roosevelt in Showtime’s upcoming anthology “The First Lady”, dramatizing the lives of several of America’s first ladies.

She also shared one of Roosevelt’s most iconic quotes: “A woman is like a tea bag: you never know how strong it is until it’s in hot water.”

Anderson is seemingly cornering the market on playing iconic women within the political realm. Her new role comes hot on the heels of her Emmy-nominated, Golden Globe- and SAG Award-winning performance as British PM Margaret Thatcher on “The Crown”.

In addition to Anderson playing Roosevelt — America’s longest-serving first lady, from 1933 until 1945 —  “The First Lady” will also feature Viola Davis as Michelle Obama and Michelle Pfeiffer as Betty Ford.

“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,” Amy Israel, executive vice-president of scripted programming at Showtime Networks Inc., said in a statement announcing Anderson’s casting.

Other stars of “The First Lady” include Kiefer Sutherland as President Franklin Delano Roosevelt, O.T. Fagbenle as President Barack Obama, and Aaron Eckhart as President Gerald Ford.
