Tyler Perry’s historical Netflix drama “The Six Triple Eight” gifts Kerry Washington with a singular role.

During WWII, America’s armed forces were still segregated, which Hitler enjoyed pointing out for supposedly being the “Land of the Free.”

Perry salutes the nation’s first and only WACs (Women’s Army Corps) unit of color to serve overseas with Washington as Major Charity Adams, commanding officer of the 6888th Central Postal Directory Battalion.

Joining the ensemble: Oprah Winfrey, Susan Sarandon and Sam Waterston.

Nicole Avant, a veteran producer (“The Black Godfather”) and former U.S. ambassador to the Bahamas who’s married to Netflix titan Ted Sarandos, brought the project to Perry who, like most everyone, had never heard of the all-Black, all-female battalion.

“I love history and I love celebrating anyone who’s been overlooked, shoved to the side,” Avant, 56, said during a virtual press conference. “If I find them, I am going to do my best to try to give them a story. What I loved about the women of ‘The Six Triple Eight’ is that they lived their greatness. Whether people acknowledged it or not.”

To portray a real-life if virtually unknown heroine, Washington, 47, felt “really lucky” that Charity Adams wrote, “A really beautiful, detailed memoir that I read too many times.” She watched “a ton” of interviews, listened to her conversations with journalists, spoke to people who knew her.

“I tried to do that deep-dive anthropological work that I love to do as an actor.  But I also had this tremendous gift: Working with a director who believed in my capacity to go somewhere I’d never gone before.

“Also,” she added, “this director is a friend. I felt really blessed to be working with Tyler on this with the voice work, the accent and the posture work.

“There was a sense of command that I felt had to come from a posture that was more deeply rooted. So I did voice work with a coach but also with Tyler to work on the accent and to make sure that there was a sense of authority in the voice.

“We talked a lot about when I’m doing these monologues. I’ve been really lucky, blessed, in my career to play other iconic women who do monologues.

“I wanted to make sure that the audience never left this world of this film and thought about anybody else. Because that felt like it would be a disrespect to the women of the 6888 and all that they gave us.

“Finding work that was grounded and came from a different part of my physicality felt like a way to live my thank you to Ms. Nicole Avant.”
