"So I've been waiting to feel less angry, and when I'm ready, I'll say what I have to say."

The clip went viral and was tweeted by Asia Argento, an actor and director who has accused Weinstein of rape.

"Dear #UmaThurman may peace be with you and your soul," she wrote. "We need your strong voice, it is truly commanding."
