Marisa Tomei had one bit part in a 1986 Miramax movie, then didn't act in a film again until 1991 (not Miramax) and, as far as I can tell never had a role in another Weinstein film. And, her career's trajectory upward had nothing to do with Weinstein as it was several years later before she hit it big.
Women get on the list by being known to be a fixture around Weinstein for some period of time, and for appearing in his wife’s Marchesa fashions. Promoting these actresses isn’t as simple as sex-for-movie-roles. He’s influential with plenty of others in Hollywood.
