Oscar nominee James Franco has the title role in Sam Raimi's "Wizard of Oz" prequel. The film centers around a young magician who is forced to flee from a traveling circus. His hot air balloon gets caught in a tornado, and he winds up in Oz, which is run by a pair of wicked witches.
In this tale, Kunis plays Theodora, a witch who starts off good, like her sister Glinda. But when Franco's character rejects her romantic advances, Theodora goes evil.
Joe Roth is producing the movie, which is slated to be released in 2013. David Lindsay-Abaire ("Rabbit Hole") revised the script.
Variety originally confirmed the casting.
