Walt Disney Pictures has released a teaser poster for Oz: The Great and Powerful, director Sam Raimi's latest directorial effort that explains how the title character in The Wizard of Oz came to be. Take a look at this one-sheet that seems to clarify how James Franco's Oscar Diggs wound up in Oz: The combination of a tornado and a hot air balloon.

OZ Poster

Disney's 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.
