Concept Art By Dylan Cole "Here is a concept painting I did of the Emerald City for Oz: The Great and Powerful. I started with a 3D base the did a ton of painting on top. A lot of the look for the courtyard area was established by Jonathan Bach and set designers." Concept Art By Daphne Yap Disney's fantastical adventure "Oz The Great and Powerful," directed by Sam Raimi, imagines the origins of L. Frank Baum's beloved character, the Wizard of Oz. When Oscar Diggs (James Franco), a small-time circus magician with dubious ethics, is hurled away from dusty Kansas to the vibrant Land of Oz, he thinks he's hit the jackpot—fame and fortune are his for the taking—that is until he meets three witches, Theodora (Mila Kunis), Evanora (Rachel Weisz) and Glinda (Michelle Williams), who are not convinced he is the great wizard everyone's been expecting.
