Probably everyone knows the story called "The wizard of Oz": Dorothy wants to escape from a fantasy world with the help of the Wizard of Oz, a powerful being that turns out to be a plain man that got there earlier.
Well... this is the story of how that wizard arrives to Oz. He turns out to be Oscar Diggs, a failed circus magician in search for glory who, by accident, ends up in the universe of the Emerald city and the yellow brick road. He thinks that this is his great chance, and pretends to be the magician of incredible powers that everyone is awaiting. But three witches, Teodora, Evanora and Glinda think he is a fraud, what will bring him great troubles.
Now that prequels are in fashion, this surprising movie arrives to the theatres. We say that it is surprising because we really weren’t expecting a movie about the wizard of Oz directed by Sam Reimi, responsible for the three first Spider-man movies. What can that mean? A darker story? A less naïve story than before? The truth is that we don’t know… and maybe that’s why we are really looking forward to see it.
There are also some people who think that Oz is a world too far away in time (the original movie dates from 1939) and that Disney is bound to have a box office failure as it happened to them with "John Carter" (which, in the end, is not a bad movie). What will happen to this one?
The only thing we can say is that you should read or watch the original version of "Wizard of Oz". If after reading it or watching it you think that you need to know more about that peculiar world of flying monkeys and precious stone cities, go ahead with this new version.
