I prefer the two books, The Marvelous Land of Oz & Ozma of Oz, to the movie from which they were drawn. Baum had a great facility for satire, which is not much shown in the movies. One of my favoite bits in The Marvelous Land of Oz is Jellia Jam (sp) translating between the Scarecrow & Jack Pumpkinhead & Kip who do not realize they are all speaking the same language anyway. Another (there and in the Wizard fo Oz) is why the Emerald City is emerald.
