McGowan says a voicemail from Harvey Weinstein after alleged rape made her vomit on herself.
"I went into a meeting at 10 a.m. and I was in the middle of my second film," McGowan recalled. "So this was my boss. And the night before, he had sat behind me in a theater where I was at a movie premiere of mine at Sundance. I was supposed to be the bell of the ball. I had four movies there that year. And I think I lasted a day and a half because I left shortly thereafter."
"Women -- and anybody who's attacked -- you just leave your body," she continued. "Everything happens so fast and so slow, because this wasn't the plan. I had turned to an MTV camera crew before going in. They were following me [shooting] a day in the life, and I did say, 'I think my life is finally getting easier.' And for years that haunted me."
McGowan said she "told everybody that day" and told them "consistently," including her manager -- who ended up working for Weinstein for seven years following the alleged incident.
"I went to the management company, the bigger managers than her, and one of them said -- and I remember it because it was so close to what Ben Affleck said, and I was kind of struck by that at the time -- and he said, 'God dammit, I told him to stop doing that. I just had an L.A. Times story killed about him. He owes it to me not to do this.'"
"Nobody cared," she said, adding that following the alleged incident, she was told by a woman from Weinstein's camp that "Nobody's gonna believe you. You're an actress. You've done a sex scene. You're done."
"There are a lot of women misogynists," McGowan said. "It's not just men."
McGowan said Weinstein contacted her three days after the alleged incident, leaving her a voicemail on her home phone.
"Somebody gave him my number -- and I won't mention the other names, but Gwyneth Paltrow's already talked about it -- and he said, 'Gwyneth's my special friend. Blank's my special friend. You're my new special friend.' And I slid down the wall and threw up on myself."
McGowan also explained why she calls the #TimesUp movement "Hollywood fakery."
"The intentions are good, but I know the people behind it, you know? It's four CAA agents who needed good PR," she said. "And I hope that they desperately help these women. I believe these women, but there's Justin Timberlake hastagging 'My wife looks hot tonight #TimesUp,' hasthtag I just did a movie with Woody Allen. So, c'mon, it is fake. I wish it weren't. I wish everybody was good. I wish it wasn't like -- I'm sorry to puncture your heroes, but sometimes these heroes need to be better."
McGowan said she goes into more detail in her upcoming E! docuseries, "Citizen Rose," where she hopes to help people overcome adversity and "hopefully teach people just to be more courageous than they already are."
Weinstein still denies McGowan's allegations of non-consensual sexual contact.
