The actress will channel the attorney and law professor in the HBO movie, "Confirmation."
"Dear @HBO, Thank you for the profound opportunity of getting to inhabit Anita Hill and help tell this story! Yours Truly, K-Dub (aka super excited Exec Producer) #Confirmation," Washington wrote on Instagram.
In the upcoming film, the "Scandal" star, 38, stars as Hill, now 58, who in 1991 accused Clarence Thomas of sexual harassment during the confirmation hearing for his nomination to be a Supreme Court justice. Wendell Pierce will play Thomas and Greg Kinnear will appear as Joe Biden. Jennifer Hudson, Cobie Smulders, Erika Christensen and Eric Stonestreet are also set to appear.
A release date has not yet been announced.
