Some 190 entertainers, academics and activists have spoken out against sexual harassment and discrimination against women in the letter that was published in the Observer on Sunday.
The actresses, who included Emma Thompson, Naomie Harris, Emma Watson and Gemma Arterton have vocally supported TIME’S UP, saying it "is bigger than just a change in our industry alone" and stating it "should be and will be a global movement."
"In 2018, we seem to have woken up in a world ripe for change. If we truly embrace this moment, a line in the sand will turn to stone," the letter reads, commending the global trend of moving forward with sexual assault allegations and the #METOO campaign.
The letter was published hours before the start of the British Academy Film Awards, a major UK event celebrating the best achievement in the movie industry. Many women attending the Sunday night ceremony are expected to appear in black, in solidarity with sexual assault victims.
