Another thought I had was that maybe Madonna won't even consider having a full-blown musical with her catalogue until she feels she's done making music, and that probably won't happen until she dies. It's one thing to let a friend use her catalogue for one special episode of Glee, and of course she has no control over the songs she does not own, but for an actual authorized musical, which will probably be a bio-musical, she probably feels it can't really be done until she's finished. I think this movie is being done thanks to that screenplay, Blonde Ambition, that Universal purchased. Maybe once Madonna publicly denounced that project, Amy Pascal of Universal contacted Madonna about doing her own movie instead of producing Blonde Ambition, and here we are now.
