A new triptych poster for Oz: The Great and Powerful has been unveiled by Disney, Digital Spy said.

The newly released image offers a look at James Franco as Oscar Diggs, Mila Kunis as the Wicked Witch of the West and Michelle Williams's Glenda the Good Witch.

Disney's fantasy epic is set before the classic 1939 film The Wizard of Oz and is centred on magician Oscar Diggs exploring the mythical Land of Oz.

Oz: The Great and Powerful also features Rachel Weisz as the Wicked Witch of the East and horror movie icon Bruce Campbell in the role of the Dark Wizard.

Spider-Man director Sam Raimi is directing the latest movie inspired by L Frank Baum's 1900 book The Wonderful Wizard of Oz.

Oz: The Great and Powerful will be released on March 8, 2013.
