Sam Raimi's upcoming fantasy imagines the origin story of the Wizard of Oz, here named Oscar Diggs and played by James Franco.
Franco's Diggs is an amoral circus magician who finds fame and fortune after being transported from Kansas into the Land of Oz, but his talents are called into question by three witches.
Mila Kunis, Rachel Weisz and Michelle Williams play the three witches who are unconvinced that Diggs can live up to his reputation, and the story sees him gradually come to earn his title as a great wizard.
Weisz has described the filming experience as "the most flat-out fun I have ever had making a film".
Meanwhile Kunis has described the Wicked Witch of the West as an "incredibly scary" role to take on.
Oz: The Great and Powerful will be released on March 8, 2013.
