Sam Raimi’s prequel to the 1939 Wizard of Oz is taking form with actors James Franco and Mila Kunis cast. The name of the film? Oz, The Great and Powerful.

The premise will tell the origins of the Wizard and the witches of Oz. So far there’s been word on the witches of the North, the East and the West — it’s not known if the Good Witch of the South makes an appearance in the new movie (she wasn’t included in the 1939 film).

James Franco is cast in the lead role as the Wizard himself, while Mila Kunis is cast as the Wicked Witch of the West, Theodorah.

Former playwright David Lindsay-Abaire is penning the screenplay for Oz, The Great and Powerful.

Franco and Kunis are a joy to watch onscreen, and it’ll be interesting how Raimi will interpret the story.
