Besides, the original film WAS a very less-than-faithful adaptation of the original Broadway "Wizard of Oz," keeping next to nothing. Imagine if the Wicked film comes out and they've cut all the songs and replaced them with a new score in "modern" trap style. Many of the characters are gone, it's just Elphaba, Galinda and the Wizard plus a bunch of new people. There's a five-second random shot of people disco dancing as the only shoutout to the Ozdust Ballroom in the original musical. That's how purists of the original Broadway Wizard of Oz would have felt about the classic film, which tossed out almost everything and then slipped in a random shot of some old-timey sailors as a nod to the "Baffin's Bay" sequence in the original musical."
The 1939 film was not remotely an "adaptation" of the 1902 Chicago/1903 Broadway show. Yeah, they swiped Glinda making it snow to counteract the power of the poppies, but that project did not start with an idea of doing a film of the show, nor, to my knowledge were rights to that version ever purchased by MGM (or any film company).
