Matt Damon says he wonders if he could have done anything to stop Harvey Weinstein.
The 65-year-old movie producer has been accused of sexually harassing and assaulting a number of women over the past 30 years and Matt - who has admitted he knew Harvey harassed Gwyneth Paltrow - said he has been questioning his own lack of action.
Speaking on the 'Today' show, he said: "I've been reading these stories because I am racking my brain. Did I see something? Could I have known something? Is there something I could've done?"
When asked if he ever thought about confronting Harvey, Matt, 47, said: "I don't know what I would've done."
Harvey helped propel Matt and his good friend Ben Affleck to fame by producing their movie 'Good Will Hunting' through his former company Miramax and Matt recently admitted he was aware of some of Harvey's transgressions but insists he had no idea about the sexual assault allegations.
'Suburbicon' star Matt told 'Good Morning America' this week: "I knew the story about Gwyneth [Paltrow] [being sexually harassed by him] from Ben, because he was with her after Brad [Pitt]. I never talked to Gwyneth about it. Ben told me. I knew that they had come to whatever agreement or understanding, she was the first lady of Miramax. He treated her incredibly respectfully. Always."
And Matt also revealed that he knew Harvey was a bully and a philanderer.
He said: "You had to spend about five minutes with him to know that he was a bully and he was intimidating...that was his whole kind of M.O. When people say 'everybody knew,' yeah I knew. I knew he was an a*****e. He was proud of that. I knew he was a womaniser. I wouldn't want to be married to the guy. This level of criminal sexual predation was not something I ever thought was going on."
