Why doesn Hollywood make more Oz movies?
In a nutshell, it’s already been done. The Movie is so well known that studio executives are generally reluctant to even consider another movie based on the Oz books. The generally poor reception of The Wiz and Return to Oz only adds to the perception. Plus, Oz just doesn’t seem to fit into the current Hollywood movie-making climate, which expects lots of aliens, laser battles, car chases, and the like for a movie — at least one that would cost as much as a live-action Oz film — to be even considered for production.
