The lovely and talented Oscar-winner Rachel Weisz is in talks to play the villainess in Oz, The Great and Powerful, Disney’s prequel to 1939’s classic The Wizard of Oz.  THR declares that Weisz would play Evanora, a wicked and powerful witch who is set on obtaining control over the land of Oz.  Directed by Sam Raimi (Spider-Man), the film will star James Franco as a traveling snake oil salesman and illusionist with a grandiose attitude.  After his hot air balloon is swept up by a tornado, he is taken to an enchanted land where he comes across real witches and eventually becomes the legendary Wizard.We previously reported that Mila Kunis would be taking on the role of Evanora’s sister, Theodora, a good witch whom Evanora coaxes into turning evil after she is rejected by Franco’s character.  The two then join forces to rule all of Oz, and Theodora ultimately becomes the Wicked Witch of the West.  Yet to be cast is the third sister, Glinda (aka the Good Witch of the North).  After Kunis was cast, Olivia Wilde, Amy Adams, Kate Beckinsale, Keira Knightley and Rebecca Hall were all reportedly on the shortlist for the remaining two sisters.  Now that Weisz is set to play Evanora, there’s a good chance that one of these five ladies will play Glinda.
