Brandeis professor Anita Hill spoke at Lesley University this week, mostly about race and gender bias, themes she deals with in her book “Reimagining Equality: Stories of Gender, Race and Finding Home.” Not addressed in great detail was the forthcoming HBO film “Confirmation,” which focuses on the 1991 confirmation hearings of Supreme Court Justice Clarence Thomas, whom Hill accused of sexual harassment when they worked together at the Equal Employment Opportunity Commission. The film, due out next year, stars Kerry Washington as Hill, Wendell Pierce as Thomas, Greg Kinnear as then-Senator Joe Biden, Treat Williams as late Senator Ted Kennedy, and Jeffrey Wright as Harvard professor Charles Ogletree, who was Hill’s legal counsel. Appearing a few weeks ago on “The Late Show With Stephen Colbert,” Washington was very hush-hush about the movie, saying only that it is a “peek behind the curtain into what was really happening” during the hearings.
