A trip back to 'Oz' just got interesting. According to sources, Mila Kunis is reportedly eying a leading role opposite James Franco in a prequel to 'The Wizard of Oz.'

According to Vulture, Kunis has turned down the lead role in Warner Bros.' 'Akira' in favor of director Sam Raimi's 'Oz, The Great and Powerful.' She is apparently interested in the role of Theodorah, who eventually becomes the infamous Wicked Witch of the West. You know, the one of "I'll get you my pretty...a your little dog too" fame.

The script, written by 'Rabbit Hole' scribe David Lindsay-Abaire, takes place long before Dorothy & Co., and follows the story of how the Wizard came to Oz and rose to power, as well as the back stories of the various witches that inhabit the fantastical land, including Theodorah and Glenda, the Good Witch of the North.
