Disney has revealed new details on Oz: The Great and Powerful, the Sam Raimi-directed remake of The Wizard of Oz.

At Disney's D23 expo this weekend, the new concept art for the film revealed the green hills of Oz along with the not-so-yellow brick road.

In the film, James Franco stars as Oz from L. Frank Baum's original story. The cast includes Zach Braff as Diggs, a circus assistant and a CGI winged monkey named Finley, who follows the great Oz on his journey. Joey King also voices a CGI character.

Disney re-released the official synopsis for the movie:

"Walt Disney Pictures' fantastical adventure Oz The Great and Powerful, directed by Sam Raimi, imagines the origins of L. Frank Baum's beloved character, the Wizard of Oz. When Oscar Diggs (James Franco), a small-time circus magician with dubious ethics, is hurled away from dusty Kansas to the vibrant Land of Oz, he thinks he's hit the jackpot -- fame and fortune are his for the taking -- that is until he meets three witches, Theodora (Mila Kunis), Evanora (Rachel Weisz) and Glinda (Michelle Williams), who are not convinced he is the great wizard everyone's been expecting. 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."

The film began shooting July 25 at Raleigh Studios in Pontiac, Mich.
