I have finished reading A Star Is Born: Judy Garland and the Film that Got Away. It is only four chapters, and it also has lots of film stills in it. But am firmly putting it in the memoir category, even though it could be cross-referenced under film, historical, because the film itself reveals so much about Judy Garland herself. And her husband Sid Luft produced it. Lorna Luft calls it a 'family home movie' and I totally get it. It's was like their own baby and her comeback film.
Lorna was actually under the care of nannies while her mother was filming for eight months or so, and by the time of the premiere, Judy was pregnant with her brother Joe. So the filming itself she has no recollection of. She first saw it on TV and then discovered that the studio had butchered Judy's creation by cutting it to make it shorter, leaving Lorna to wonder about all the holes in the plot. Judy was nominated for an academy award for this movie, but the Oscar did not go to her or any of the makers, and for this, Judy (and Sid) felt totally betrayed because they put EVERYTHING into it. The film itself is an extravaganza and totally eclipses all the musicals Judy had ever starred in before, mostly because it's about her becoming a star and deals with addiction and dreams, all the magic Hollywood is known for, and the awful price she pays.
Lorna writes with the help of film historian Jeremy Vance piecing the films genesis together, it's reception to a movie-going public and various incarnations, so Barbara Striesand's version also gets details. I would skip that chapter if you not interested. Then it's 1983 restoration and 2010 digital remastering. Husband Sid died in 2005, but not before being acrimonious with daughter Lorna for publishing her own book about her mother (he was jealous, cos he hadn't written it himself) . The part of the book I most got was closure, in 2017 Judy's remains, her body was reinterred from New York to a Hollywood cemetery with the consent of her family. She's finally at rest where she belongs, although what she gave, her talent and her voice, the legacy of her films, belong to everyone.
