This 1933 version of "The Wizard of Oz" is quite short but it's surprising to see it today because its filmed in lovely color--colors that were quite dramatic for 1933--especially the blues. This appears to be true Technicolor--not the Two-Color Technicolor used in the 1920s and 30s and I was surprised it was in use that early (since it wasn't used in live action films until 1934 and 1935).
The film begins in a black & white Kansas and soon a tornado brings Dorothy and her home to Oz--and the film switches to color! I was surprised at this, as this technique was the same one used in the famous 1939 film and appears to have inspired them. As for the story, it's so abbreviated and told without dialog and has little to do with the original novels. So, it's very, very hard to compare this to any other Oz story and you have to accept it for what it is. It's a bit too cutesy for me, but technically speaking it's a marvelous little film. It is certainly not brilliant when seen today, but for 1933 it's awfully good.
