I just realized that there's been no mention of Nora Ephron, which is a bit surprising in a women's forum, since I suppose she's been the most successful mainstream woman filmmaker. Are you aware of her, and aware that she just died unexpectedly?
Some of her movies:
Silkwood (co-writer)
Heartburn (writer)
When Harry Met Sally (writer)
Sleepless in Seattle (writer and director)
Michael (writer and director)
You've Got Mail (writer and director)
Julie & Julia (writer and director)
