The Wizard of Oz isn’t just an influential movie, it’s the influential movie. Buena Vista/Kobal/ShutterstockReturn to Oz is a movie that, by all accounts, shouldn’t have worked. The idea for a new Oz movie came from Walter Murch, who at the time was known best as the editor behind Apocalypse Now, The Godfather trilogy, THX 1138, and American Graffiti. As it happens, Disney’s ownership of the Wizard of Oz books was about to expire, so a movie based on the original books would be perfect for the studio. Who can say if it changed the franchise for the better, but it definitely changed it for good.
