As Portman announced the nominees, she went off-script and said, "Here are the all-male nominees."
Her startled co-presenter, director Ron Howard, laughed nervously, and each of the nominated directors looked uncomfortable when the camera found them as their names were announced.
Sexism and inequality was the theme of the night, with stars wearing black and wearing pins supporting Time's Up, a legal defense fund for women who speak out against sexual harassment in the workplace, and numerous speeches addressing issues of inequality.

Social media was loving Portman's call-out.
