Quentin Tarantino, the Hollywood director most closely tied to Harvey Weinstein, has known for decades about the producer’s alleged misconduct toward women and now feels ashamed he did not take a stronger stand and stop working with him, he said in an interview.

“I knew enough to do more than I did,” he said, citing several episodes involving prominent actresses. “There was more to it than just the normal rumors, the normal gossip. It wasn’t secondhand. I knew he did a couple of these things.”…

When he and Ms. Sorvino started dating in 1995, she told him that not long before, Mr. Weinstein had massaged her without asking, chased her around a hotel room and even showed up at her apartment in the middle of the night, a story she recently shared with The New Yorker.

“I was shocked and appalled” back then, Mr. Tarantino said. “I couldn’t believe he would do that so openly. I was like: ‘Really? Really?’ But the thing I thought then, at the time, was that he was particularly hung up on Mira.”
