Following their Hall H panel at Comic-Con, director Sam Raimi, along with actresses Mila Kunis and Michelle Williams, held a press conference to discuss the new film Oz: The Great and Powerful, which already looks intriguing and compelling, just from its small glimpses.  The story is a prequel to the classic Wizard of Oz, telling how the selfish Wizard (played by James Franco) arrived in Oz from Kansas and went on to become a more selfless ruler and man.  Check out what they had to say after the jump.
