No story details have been released for the sequel, but there are a few things that the writer legally cannot include in the story. L. Frank Baum's novel The Wonderful Wizard of Oz is in the public domain, which means the writer can use anything contained in that book. However, he cannot use any of the additions used by Warner Bros. in the 1939 classic The Wizard of Oz, such as Dorothy's ruby slippers.
The studio hired Mitchell Kapner to work on the sequel script months ago, a sign that Disney is very confident Oz: The Great and Powerful will be a hit. The movie stars James Franco as Oscar Diggs, a Kansas magician who is transported to the mystical land of Oz, where many believe he is the chosen one who can defeat the Wicked Witch. Mila Kunis, Rachel Weisz, and Michelle Williams also star as the witch sisters Theodora, Evanora, and Glinda. Disney would not comment on the sequel plans at this time.
Mitchell Kapner's other screenwriting credits include The Whole Nine Yards, The Whole Ten Yards, and Romeo Must Die.
Oz: The Great and Powerful was released March 8th, 2013 and stars James Franco, Mila Kunis, Rachel Weisz, Michelle Williams, Zach Braff, Bill Cobbs, Joey King, Tony Cox. The film is directed by Sam Raimi.
