8. The Wizard Of Oz Like Citizen Kane, The Wizard Of Oz is frequently listed as one of the most important movies ever made. Watching it and it's not hard to see how it has earned this reputation - the wonderful transition from black and white to glorious technicolor alone is an iconic moment in the history of cinema. But again, as with Citizen Kane this is an old film, which means that an increasing number of new, younger movie fans out there are perhaps unlikely to have seen it, despite the fact that it remains a regular fixture on television channels around the world. Nevertheless, chances are they're more than familiar with the characters and the award-winning ballad, Over The Rainbow. Missing out on The Wizard Of Oz is essentially missing out on the birth of fantasy cinema which has become utterly engrained in American popular culture - perhaps the most amazing thing about it is the fact that, considering its vast legacy today, The Wizard Of Oz was not particularly successful when it was first released.
