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.”

“I wish I had taken responsibility for what I heard,” he added. “If I had done the work I should have done then, I would have had to not work with him.”
