Is the script (or scripts) from the proposed Fox pilot available for reading?
I don't believe so. DC's estate probably has a copy of it packed away somewhere - but DC was involved in writing it, so once again it was yet another reworking of hoDS.
The scripts I would have liked to have read were the two that were written for the proposed theartrical versions of the '91 DS (one script for the present day action, and one for the 1790 action). At least with those, DC was involved with writing them, but so was Barbara Steele, and she made sure new twists and turns were put into them rather than simply being a remake of the '91 series for theaters...
