Did you hear? Robert Downey Jr. is rumored to be a contendah for the role of the Wizard in the upcoming prequel to "The Wizard of Oz." Blasphemy! you might say, but stay calm, no one's trying to remake the 1939 Judy Garland version (not yet, anyway). Though this new film (titled "Oz: The Great and Powerful") takes place before the Wiz became the Wiz, this bit of news got us thinking: who would we cast if someone somewhere was crazy enough to try and touch the original? So sit back, relax and click through to see who we'd cast in a contemporary remake of the beloved classic.
