"I knew enough to do more than I did," the director, who has worked with Weinstein throughout his career, told The New York Times in an article published Thursday.
"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," he continued.
Tarantino says he was aware of Weinstein's sexual advances towards actress Mira Sorvino in 1995, whom the filmmaker was dating at the time. "I was shocked an appalled," Tarantino said of Sorvino telling him Weinstein had chased her around a hotel room and showed up at her apartment in the middle of the night.
