Michelle Williams, Rachel Weisz, and Mila Kunis, will all return with Franco.
Disney has officially already approved plans for a sequel film to "Oz the Great and Powerful". James Franco, Mila Kunis, Rachel Weisz, and Michelle Williams are all signed on for multiple sequels. Mitchell Kapner was contracted several months ago to write the screenplay for the next film in the Oz franchise. Aside from writing the screenplay for "Oz the Great and Powerful," Kapner wrote screenplays for the Warner Bros. Pictures feature films "The Whole Nine Yards" and "The Whole Ten Yards" both starring Bruce Willis and Matthew Perry, "Romeo Must Die" starring Jet Li, and the MGM Home Entertainment direct-to-video "Into the Blue 2: The Reef".

Although Mitchell Kapner can not use any of the iconic creative additions from the Warner Bros. owned 1939 film "The Wizard of Oz" such as the red slippers, he is free to tap into any material that is featured in L. Frank Baum’s novel "The Wonderful Wizard of Oz" or any of the fourteen Oz books, all of which are in the public domain in the United States. He is free to have Dorothy wear silver slippers, because that is the color of her slippers in the novel. George M. Hill Company published "The Wonderful Wizard of Oz," and and Reilly & Britton published the remaining Oz novels.

A reboot of the 1939 film would be vastly different, contrary to many uninformed website articles. Just as "Oz the Great and Powerful" is a more "faithful" adaptation of the source material than the 1939 film "The Wizard of Oz", the sequel will follow in this same form. For instance, in the novels Oz is a real place, not a dream. In another example, The Good Witch of the North (who has no name in the book), Glinda the Good Witch of the South, and the Queen of the Field Mice are merged into one omniscient character, Glinda the Good Witch of the North. There are at least 44 identifiable major differences between the original book and the 1939 movie interpretation.

Oz: the Great and Powerful" follows Oscar Diggs (James Franco) who meets three witches, Theodora (Mila Kunis), Evanora (Rachel Weisz) and Glinda (Michelle Williams). Reluctantly drawn into the epic problems facing the Land of Oz and its inhabitants, Oscar must find out who is good and who is evil before it is too late. Putting his magical arts to use through illusion, ingenuity and even a bit of wizardry, Oscar transforms himself not only into the great and powerful Wizard of Oz but into a better man as well. "Oz the Great and Powerful" was released by Walt Disney Pictures on March 8, 2013, in conventional 2D, as well as in the Disney Digital 3D, RealD 3D and IMAX 3D formats. The film captured the #1 position at the box office raking in an amazing 80.3 million.

Golden Globe Award nominee Mila Kunis, who plays the witch Theodora in "Oz the Great and Powerful", has confirmed that she and the other three main cast members have all signed on to appear in multiple sequels. Disney is planning on fast tracking this "Oz the Great and Powerful" sequel in order to get the film into theaters as soon as possible, especially as it turns to well-established brands and characters as the basis for its high-profile tentpoles. Similar fantasy films in development at the studio include “Maleficent,” based on “Sleeping Beauty,” and “Cinderella.”
