Transcript for 'Game of Thrones' actor Esme Bianco discusses alleged abuse by Marilyn Manson
I was a prisoner in his hell, yet I thought I had done something to deserve it, so I just tried harder to please him. Reporter: Esme Bianco first went public with allegations she had been abused when she testified in 2019. The physical violence was disguised in acts of intimacy and was not consented to. Reporter: At that time she didn't name the man she says is responsible. But today that changes. Were you abused by Marilyn Manson? Yes, I was. How long did it take you to realize that's what was happening? Seven years after I left. It's not easy for girls like us to dig our way out. Reporter: Bianco is best known for her role in "Game of thrones." But her career began as a model and burlesque performer in London. In 2005 she was introduced to Marilyn Manson. The controversial global rock star who she idolized as a teenager. How did you first come into Marilyn Manson's orbit? I was introduced to him by his then fiancee. When I spoke with him for the first time, the first words out of his mouth were, "I've been a fan of yours for years." Reporter: Over the next four years she says they built a friendship based on mutual interest in art and music. He gained her trust. In 2009, she says Manson asked her to star in a music video he was making and flew her from London to L.A. He told me we were going to shoot on flip cams so we could do it ourselves. That was the beginning of the nightmare. Reporter: This is when she says Manson was first violent with her. It got to the stage where he wanted to shoot the finale of the video, and he locked me in his bedroom, and he tied me to a wooden prayer kneeler. I was half naked. And he beat me with a whip. Reporter: Bianco provided ABC news with this photo which she says is her back marked with whiplashes after the incident. At any point did you ask him to stop? No. I would never have dared to ask him to stop. Was there ever a point where you feared for your life? The entire time during that shoot. Reporter: Over the following two years, she says the relationship became sexual. He would hide abuse by doing it during sex, basically. He always went too far. The biting. That was 100% nonconsensual. And he would bite me till I was black and blue. Why continue to go back? I thought he was in love with me. Because I did not understand that what was happening to me was very, very wrong. And because he was incredibly manipulative. Why didn't I just run? What was I doing? It's not until we truly understand what psychological abuse and gaslighting does to somebody that you can fathom why I would have stayed. Reporter: Then in 2011, with the promise of a committed relationship with Manson, she says she moved into his los Angeles apartment. She -- controlled every aspect of my life. I was isolated very quickly. I had a dress code I was expected to abide by. What was that? Heels, lingerie, stockings. I wasn't allowed to come out of the bedroom until I was fully hair, makeup, the whole shebang. And he had people that all of the time -- he has an entourage of people. The expectation was that when he said so, I would be paraded out of the bedroom. There would be times he'd pull up my dress to show them bruises on my butt or whatever it might be. That he'd given you? That he'd given me. He was proud of it? He was proud of it. Yeah. Reporter: Bianco says months of controlling and abusive behavior by Manson culminated in one terrifying night. He thought I had put cockroaches in the walls to mess with him. And he took an ax and he started smashing holes in the walls. And then he started chasing me with the ax. And at that point I thought, he's going to kill me. Reporter: ABC news spoke with a former assistant of Manson's, Ashley Walters, who said she saw Manson chase Bianco through the apartment with an ax and recalled seeing bruises on Bianco's body while she was living there. Bianco is the first of Manson's accusers to share her story on camera, but several women have come forward on social media, including actress Evan Rachel wood, with similar allegations in the past two weeks. In response Monson released a statement categorically denying the claims against him. He calls them horrible distortions of reality. And his statement in part reads that his relationships have always been entirely consensual with like-minded partners. It's disgusting that that is his response. That somehow we're the ones who business-construed the whole situation? It's very indicative of the kind of man he is. The monster that he is. Reporter: ABC news reached out to Manson and his representatives multiple times for comment on Bianco's specific allegations, but we have not heard back. Bianco's attorney provided a statement saying she's been interviewed by and given evidence to federal investigators about her allegations against Manson. Now you're cooperating with law enforcement, correct? Why are you doing that? Because I want him to be held to account. I want to make sure that he sees justice. And, you know, whatever I can do to help law enforcement with their inquiries, you know, I'm going to cooperate. Frankly, I think he deserves to be behind bars for the recess S life. Reporter: Her lawyer says Manson's treatment of Bianco, including asking her to travel across international borders, constitutes human trafficking. I was defrauded. I was transported from the uk to the U.S. I was harbored. And then I was coerced into involuntary servitude which included sexual abuse and physical abuse. How does it feel now to be able to name him? It's like a massive relief. At the same time, it's -- it's terrifying. I'm still scared of him. I'm still scared of retaliation. Where do you find that strength? I think it comes from thinking about other survivors. Perhaps I can give strength to another survivor to go and report. And I want people who are in this situation right now to know they're not alone and that it's
