Journeys to the Land of Oz have been few and far between when it comes to the world of cinema. Many projects have been in development over the years, but none of them can get off the ground. It's not hard to understand why. MGM's 1939 musical version has long been recognized as the definitive film version of L. Frank Baum's magical tale. Walter Murch's attempt at a sequel fell flat in 1986, even though "Return to Oz" has gained a cult following over the years. Walt Disney Pictures has successfully beaten MGM to the punch by providing what I and many others will see as the "official" unofficial prequel to the original.
