"Dylan Farrow's two different pieces made me realize that I increased another woman's pain, and I was heartbroken by that realization", said Gerwig, who had previously evaded questions about whether she would work with Allen again.
"Their reception?", Gerwig spoke about working with Allen in the 2012 romantic comedy film To Rome with Love, a fact that has been brought up a lot recently in light of "Time's Up" supporters getting called out for their support of the director.
"I can only speak for myself and what I've come to is this: If I had known then what I know now, I would not have acted in the film", she said. "I have not worked for him again, and I will not work for him again".
"Thank you for your words".
"It's of course particularly hard for me as a survivor of sexual abuse to know that for these particular individuals I am not part of the "every woman" they stand for", Farrow said.
Speaking in the winners' room, Greta said: "It's something that I've thought deeply about and I care deeply about and I haven't had an opportunity to have an in-depth discussion where I come down on one side or the other".
Gerwig starred in 2012's To Rome With Love, and was asked about the topic of Allen's allegations a number of times.
"But he knew and I knew that it was a moral issue", she continued.
Allen has never been found guilty of child sex abuse.
"I struggle to understand how a woman who believes Woody Allen is "empowering to women" can claim the role as an advocate for women suffering from sexual harassment", Farrow said. "I made an terrible mistake". But I have to wonder - is time really up now? I have no doubt the time is right.
That apparently changed in short order. "The principles of the movement need to be applied consistently and without exemption".
Gerwig's comments come following the online backlash Justin Timberlake received for wearing a Time's Up badge at the Golden Globes due to his involvement in Allen's latest film.
