Some years ago I was hunting information on the subject of Saban Moon and actually emailed Rocky Solotoff, the guy in that interview. I can't remember how I tracked him down, but he might be
http://www.toonmakers.com/ He was very nice and answered my questions with the following info:
-there was one 17-minute episode made
-it still exists, in some safe place
(he wouldn't say where, probably in case I knew any fans who were also burglars.)
-he didn't know who owns the rights
(according to copyright.gov, TOEI seems to have bought the rights, but I could be misreading the site)
-it was a cheaply made concept video, not meant to be shown on TV
-the plot would have featured the girls going to private school on the east coast, and legal reasons prevented him from revealing more of the plot & characters.
So there's another snipped of information for the thread.
