In many ways her allegation helped ignite a firestorm. Now more than 65 women have come forward and she spoke one-on-one to our Diane sawyer. Good to see you. Great to see you, robin. You're exactly right. It kind of lit a fire across this country among women of all professions, every part of the nation when they heard the story of Ashley Judd and the women in Hollywood and the man who was standing at the gateway of their work and their dreams. Ashley Judd, who says for the women who came forward it's not about fearlessness but taking action despite your fears. Well, here we are. Did you ever imagine a day in which so many people would be talking about something inside you for so long? Well, first of all, I'm very blessed to be here and I know that so thank you and I didn't expect that I would feel tearful but it's been an absolutely tremendously moving 2 1/2 or 3 weeks. Reporter: She says before she decided to speak out, it was frightening, not clear whether anyone would believe the women or anyone would care. I went on a run and I thought, sometimes people say they pray on runs or get clarity about things and use it to process and sort and so that's what I did on this particular run on peach hollow road. One of high favorite country roads. I made the most important decision I'll ever make years ago which is to turn my will and my life over to the care of a loving god and it was like, I'm so taken care of. I'm totally going to do this. I also talked with my dad and when I talked with my mom I told her what I was thinking of doing and she said, go get 'em. ??? Love can be ??? Reporter: Mom would be Naomi Judd, who with her daughter Winona was already part of a legendary singing duo, but the youngest daughter Ashley says she had a different idea she got in her banged up car, left Kentucky to act and tell the stories of people she loved. Your people being. Good old hillbilly, appalachian folk, yes. Yes. Reporter: In Hollywood she says she got some small parts. Then larger ones. And she got the attention of one of the reigning titans of the business, producer Harvey Weinstein. Of the more than 60 women who have come Ford to say they were his prey nearly 20 say it happened before a girl named Ashley Judd says she entered his hotel room. He had called, wanted to talk to you. Had you heard about him? Had you heard anything about him? I mean, heard to be wary? No, I had not. No, I had no warning. I had no warning. I remember the lurch when I went to the desk and I said Mr. Weinstein, is owe on the patio and they said he's in his room and I was like, oh, you're kidding me. But you went up because? I had a business appointment. Which is as that is his pattern of sexual predation is how he rolled. Reporter: She already knew something about sexual predation. She's written about being sexually assaulted when she was young and the terror you feel before you're trapped. And in a pattern so many women say happened to them too she says the man inside began insistent pressure. There's this constant grooming, negotiation going on, I thought no meant no. Reporter: She said he first asked to give her a massage because she was tired and asked for her to give him one. Volley of noes. Maybe he herd them as yeses. Maybe it turned them on. Reporter: He steered her into a hallway near a closet. 'S of coursed me to pick out his suit for the day. Reporter: She remembers the bathroom just ahead. No exit. You know, I have totally frozen in my mind the floor plan and where the door was behind me and then eventually where that closet was. Reporter: She says she wouldn't sit down. She remained standing as she wowered in the hall five to seven minutes and says at one point he asked her to come into the bathroom and watch him take a shower. I had with me a list of the different defenses that women who have come forward say they tried to use to escape. That like tone of voice designed thought to offend swung powerful. Laughing. Frozen. Panicked. One person said I sang. Yeah. I just started singing. We act like we're about -- between 3 and 6 years old in those moments. Reporter: But she has an idea make a deal and encounter someday. He kept coming back at me with all this other stuff and finally I just said, when I win an Oscar in one of your movie, okay. When you get nominated. I said, no, when I win an Oscar and then I just fled and then I just fled, which I think, you know, am I proud of that, I'm of two minds, the part that shapes myself says no. The part of me that understands the way shame works says that was absolutely brilliant, good job, kid. You got out of there. Well done. It's a very important word, shame and it's a very important thing to talk about so we all do the best we can and our best is good enough. And it's really okay to have responded however we responded. Reporter: She says afterwards she had trouble grass. ING what had happened but told her parents enough they could see how shaken she was. And she told other people in private, agents, actors. People would worked in Hollywood at a time when Hollywood turned a blind eye. And if I could go back retrospectively with a magic wand and say, I wish I could prevent -- I wish I could prevent it for anyone always, I don't know that I would have been believed and who was I to tell? I knew it was disgusting. Like was I going to sell the concierge who sent me up to the room. Reporter: There were photos from the time, the "Vanity fair" Oscar party. This one released to us by Harvey Weinstein. He put up this picture. Ick. This shows that you were friends that you were fine. That he even tried to fix you up with his brother or did fix you up with his brother. She says they had tea in public. So you were friends. No. That's, deny, attack, reverse the order of offender and victim. Reporter: And she points to a different picture from that same event and I hoped I wouldn't pass him. But I did and he obviously grabbed my hand. It's like the look on my face is abject terror. Like I can see it in my eyes. Your elbow. It seems to be pushing him back while you're holding his hand. Yeah. It's very -- it's very gross. It's very gross. I feel for that 28-year-old, 29-year-old woman. There's so much more coming up and -- and she has something she wants to say to him today and I think it will not be probably what you think she's going to say. I know it caught you by surprise when she said it to you. It did. E see her now, composed woman. But how she explained and even referring to her back then as a kid she just wanted to make movies about her people as she said. It's true. Kentucky girls. Right. Right. Both of us Kentucky girls but also coming up you're going to see what happens. We have some women around the country who have sent us audiotapes. We play them for her. People who they're fearful -- Do not even have her voice. Who -- their names will never be known. So much for of Diane's revealing interview coming up in our next hour and we will hear from women all across the country. Their story. Just incredible. Thanks, Diane. Thanks Diane.
