Revealing mistake: When the Wicked Witch scares the Munchkins in Munchkinland, where Dorothy lands, she disappears into a cloud of smoke she creates. But you can see her sneak down into a trap door below. [As a sidenote to this entry, Margaret Hamilton was hospitalized for severe burns after a take of this shot (not the final one used) when there was a glitch in the timing of the explosion.]
Question: More of an observation than a question, but it has occurred to me that the movie leaves a rather significant loose end unresolved. At the beginning of the film, Miss Gulch is going to have Toto destroyed. Nothing happens to change that. Dorothy's adventure/dream in Oz didn't get rid of the real woman back in Kansas who wants her dog dead. Am I missing something, or are we just to assume that because Toto got free from the basket, Miss Gulch didn't notice?
