Character mistake: While singing the "If I Were King" song, the Lion asks, "What makes the Sphinx the Seventh Wonder?" The Sphinx is not one of the Seven Wonders of the World; its neighbour the Great Pyramid of Giza is. Besides, how would the residents of Oz know about our Seven Wonders of the World? (01:07:00)
Continuity mistake: As Dorothy and the Scarecrow dance off and sing, "We're off to see the Wizard" the flowers that were on the fencepost have been removed. The stepladder by the fence has also been moved without being touched. (00:38:55)????
