Years later those threats came back to haunt Morton when she was set to be cast in 2005's 'The Brothers Grimm' but Weinstein used his influence to get her off the project.
She added: "There was a film called 'About Adam' that was being shot in Ireland and I had a threat to me that said, if I didn't do a part in that film, I would never work again. And I didn't want to do the part.
"Apparently. [A threat of], 'This will ruin your career, and nobody says no to him.' And I did. Then years later they wanted to cast me in 'The Brothers Grimm' ... But there was some things said about me [by him] that were then published, to do with me, 'Not being f**kable'.
"That's when the line was crossed for me. You cannot cast me because I'm not good, or not right for the part. But to say [it's because] I'm not f**kable - it's the most disgusting, horrible [thing]."
'The Walking Dead' star admits she had heard rumours about actresses getting roles by performing sexual favours for Weinstein - who has been accused by multiple women of sexual assault and harassment.
She said: "I was on a job once and an actress was doing this part and then suddenly was removed from the film while another person was flown in overnight. The rumour was she'd given him a b**wjob for the part - that's what you needed to do to get in Harvey's gang."
