Amanda White claims Affleck acted inappropriately while directing I'm Still Here and she is suing him for $2 million (GBP1.3 million).
In papers filed in Los Angeles on Friday, White alleges she endured "uninvited and unwelcome sexual advances in the workplace" while making the movie.
She claims Affleck referred to women as 'cows' and discussed his sexual exploits in front of her. The producer also alleges Affleck, who is married to Phoenix's sister Summer, and the film's star took over her hotel room in Costa Rica one night to entertain two women; and the director attempted to get her to spend the night with him in his hotel room in San Francisco, California.
In the lawsuit, White claims Affleck became "hostile and aggressive" when she turned him down and "violently grabbed her arm in an effort to intimidate her into staying."
The producer has a list of damages, which includes sexual harassment, breach of oral contract and intentional infliction of emotional distress.
She also claims Affleck owes her money for her services as producer on I'm Still Here.
