Weinstein has now resigned from the board of the company he co-founded with his brother
Game of Thrones star Lena Headey has claimed Harvey Weinstein angrily marched her out of a hotel after she rejected his advances.
The British actress posted a series of tweets in which she detailed meetings between the two where the Hollywood mogul allegedly made "suggestive" comments towards her and became enraged after she rejected his advances.
It comes as Weinstein has resigned from the board of The Weinstein Company - the film studio he co-founded in 2005.
The 65-year-old reportedly owns an approximate 20% stake of the company, which is in talks with Colony Capital over a potential buyout.
Headey, who plays Cersei Lannister, said she first met Weinstein at the Venice Film Festival.
She wrote: "Harvey asked me to take a walk down to the water, I walked down with him and he stopped and made some suggestive comment, a gesture, I just laughed it off, I was genuinely shocked.
"I said something like, oh come on mate?! It'd be like kissing my dad!"
Headey said in another meeting at a Los Angeles hotel about potential work, the pair talked about films before the producer turned his attention to the "state of my love life".
"I shifted the conversation back to something less personal," Headey wrote.
She claimed Harvey Weinstein then asked her up to his room to give her a film script.
The actress said Weinstein was "silent" and "furious" as they walked towards his room.
She said: "His hand was on my back, he was marching me forward, not a word, I felt completely powerless, he tried his key card and it didn't work, then he got really angry.
"He walked me back to the lift, through the hotel to the valet, by grabbing and holding tightly to the back of my arm, he paid for my car and whispered in my ear, don't tell anyone about this, not your manager, not your agent.
"I got into my car and I cried."
A series of women - including Gwyneth Paltrow, Cara Delevingne and Ashley Judd - have accused Weinstein of sexual harassment.
The producer has "unequivocally denied" the claims against him.
Meanwhile, the boss of Amazon Studios has also resigned over the scandal.
Roy Price was accused of ignoring allegations from an actress about the disgraced producer.
