Director Sam Raimi has tapped Michelle Williams to play Good Witch Glenda in the Wizard of Oz prequel, Oz, the Great and Powerful. She’ll team up with James Franco’s wizard to do battle against evil sisters Rachel Weisz (the Wicked Witch of the East) and Mila Kunis (The Wicked Witch of the West). That’s a very good-looking coven. [Movieline]
