MGM’S 1939 adaption of The Wizard of Oz is one of the all time classics. A film that can be enjoyed by children and adults alike, is as well received now as it was seventy five years ago. It’s astonishing that Dorothy walking into Munchkin land gives the same response, of excitement and thrill from the audience, as when Harry walks into the magical Great Hall at Hogwarts, and Oz was made a long time before anybody ever uttered the letters “CGI”.

From all my research into the making of The Wizard of Oz, I’ve never been able the find the answer I’ve been looking for, and that is why in the film was Oz changed to part of a dream Dorothy had after getting knocked out, unlike in the books by L. Frank Baum, where Oz is a real place that Dorothy eventually returns to.
