I'm sure you all knew that Judy Garland was originally going to be cast as "Helen" in the VOD movie (ironyyyy)... Here are a couple links to related videos via Youtube.
Judy's pre-recording of "I'll Plant My Own Tree" put to clips from her tv series, wardrobe tests for VOD, and still pictures. (LINK)

"Judy hadn't read "Valley" and was in for a big surprise once shooting started. This will probably be deleted, but yes... the rumors of Jackie Susann and Judy having a brief fling were accurate. According to Jackie's husband, out of pity, Jackie gave Judy $800. Neither Jackie nor her husband ever publicly admitted the truth- that much of "Valley" was about Judy."
