Who is the Wicked Witch? Walt Disney Pictures has unveiled a new clip from Oz: The Great and Powerful, which hints that Mila Kunis' Theodora may be the most vile and hated witch of Oz. While Theodora doesn't completely undergo her green-skinned transformation in this scene, we do see some of her "wicked" rage boiling to the surface during an argument with her sister Evanora (Rachel Weisz). Do you think Theodora is, in fact, the Wicked Witch in director Sam Raimi's magical adventure? Take a look and decide for yourself.
