Walt Disney Pictures has unveiled a revealing first TV spot for Oz: The Great and Powerful, director Sam Raimi's new adventure that explores what happened before L. Frank Baum's timeless tale, The Wizard of Oz. Before becoming the man behind the curtain, Oscar Diggs (James Franco) is a small-time circus magician who finds himself in the land of Oz, where he meets the witches Evanora (Rachel Weisz), Theordora (Rachel Weisz), and Glinda (Michelle Williams). While this video sheds more light on the sisters, the ultimate question still remains: Who is the Wicked Witch?
