"I feel that I'm not worthy. I wish I could be better to live up to the character that Viola has to play, but it's exciting," she said.
"Anything Viola does, she does it with passion and vigor, and I know she will do no less for this role," she added about the actress, who this week received an Oscar nomination for her role in the Netflix film Ma Rainey's Black Bottom.

Viola herself admitted she was feeling "a little scared" about taking on the role back in 2019 when the project was first announced.
"She's smart. She's confident. She's articulate. She believes in sisterhood," she said. "I wanna honor her. I wanna honor her with this portrayal because that's what drama is. That's what we do as actors, we want to honor the human being. We don't want to give a portrayal that isn't easy for people to swallow."
O-T Fagbenle will star opposite as Barack
Starring opposite Viola as President Barack Obama is British actor O-T Fagbenle, best known for his role of Luke in The Handmaid's Tale. Little Fires Everywhere breakout star Lexi Underwood has also joined the cast, playing Michella and Barack's eldest daughter, Malia. It is not known who will portray the couple's younger daughter, Sasha.

"This series will peel back the curtain on the personal and political lives of these enigmatic women, with season one focusing on Eleanor Roosevelt, Betty Ford and Michelle Obama."
