For the record, Peter Jackson says that Weinstein "blacklisted" two actresses whom he claimed were hard to work with. These actresses later accused him of sexual impropriety. So the film trilogy is sadly not entirely clean of his influence. But I haven't found anything to suggest that the actresses who actually worked with PJ and Co were affected by him.
