Not surprising since I've already noted the lack of women overall behind the camera in Hollywood, such as the abysmally low percentage of women directors (4-5%)... but I was curious how much was the most a woman had ever been paid for a screenplay.
Look at the following:
Top 11 Highest Paid Screenwriters
Highest Paid Screenwriters
In the first list, there are no women.
In the second, there is one woman's name attached to a produced screenplay - but the other (2 or 3) mentions of women on the second two pages are all for unproduced work. In fact, the highest amount offered to a woman was offered on the condition she step away from a project she'd written for herself - and she refused. (It hardly counts if she didn't even take the money.) All of the women on the list had male collaborators. The single produced script was co-authored by Anne-Marie Crichton and her husband - Michael... I feel somewhat certain it would have sold for as much without her name attached.
In response to this, I declare my intention to have the record for the most paid to a woman for a produced screenplay. So there.
