Joining a growing roster of celebrities, Emma Watson and Colin Firth have come forward to condemn Harvey Weinstein and applaud the women who have spoken out about Weinstein’s alleged sexual harassment and misconduct.

Watson, who worked with Weinstein on her 2011 film “My Week with Marilyn,” tweeted that she “stands with all the women who have been sexually harassed, and am awestruck by their bravery.” She did not say whether she herself had been subjected to or witnessed Weinstein’s alleged abuse.

“This mistreatment of women has to stop,” said Watson, who is known to be a strong advocate for women’s rights and was named a Women Goodwill Ambassador for the United Nations in 2014. The 27-year-old Harry Potter star said she also stood with “all the men, indeed any person, who has suffered sexual harassment.”

Firth, who worked with Weinstein in 2011 on “The King’s Speech” and won an Oscar for his performance, told the Guardian newspaper that the producer “was a powerful and frightening man to stand up to.”

“It’s with a feeling of nausea that I read what was going on while I was benefiting from Harvey Weinstein’s support. He was a powerful and frightening man to stand up to,” said Firth, who also worked with Weinstein on Oscar-winning titles “The English Patient” and “Shakespeare in Love.” “It must have been terrifying for these women to step up and call him out. And horrifying to be subjected to that kind of harassment. I applaud their courage.”

“I’m just saddened and appalled by what I hear – never witnessed anything but saddened and appalled,” said Kristin Scott Thomas, who starred in Miramax’s “The English Patient.”
