Mila Kunis has signed on to star in "The Wizard of Oz" prequel, called "Oz: The Great and Powerful" and will be directed by Sam Raimi (Spider-Man). Now that Kunis is on board, James Franco decided to sign on as well. He will play the young wizard.
"Oz" tells the story of the origins of the Wizard, and the infamous witches like Glinda, who becomes the Good Witch of the North, and Evanorah, who becomes the Wicked Witch of the East.
Kunis will play Theodorah, the younger sister of Evanorah who goes on to become the Wicked Witch of the West and, of course, to cackle iconic lines like, "I'll get you, my pretty ... and your little dog, too!"
