“I was a kid, I was signed up, I was petrified,” she said in an interview, publicly disclosing that she was sexually harassed by the man who ignited her career and later helped her win an Academy Award.

She refused his advances, she said, and confided in Brad Pitt, her boyfriend at the time. Mr. Pitt confronted Mr. Weinstein, and soon after, the producer threatened her not to tell anyone else about his come-on. “I thought he was going to fire me,” she said.

Rosanna Arquette, a star of “Pulp Fiction,” has a similar account of Mr. Weinstein’s behavior, as does Judith Godrèche, a leading French actress. So does Angelina Jolie, who said that during the release of “Playing by Heart” in the late 1990s, he made unwanted advances on her in a hotel room, which she rejected.

“I had a bad experience with Harvey Weinstein in my youth, and as a result, chose never to work with him again and warn others when they did,” Ms. Jolie said in an email. “This behavior towards women in any field, any country is unacceptable.”
