Emma Watson has donated £1m to a new campaign aiming to help those affected by sexual harassment.
Let’s make 2018 the year that time was up on sexual harassment and abuse.
The letter says Sunday’s Bafta awards ceremony is a time to “celebrate this tremendous moment of solidarity and unity across borders by coming together and making this movement international”.
Emma Thompson, Carey Mulligan, Saoirse Ronan, Gemma Chan, Knightley and Watson are among the actors to sign the letter, which was published in The Observer.
