The marketing campaign for director Sam Raimi’s fantasy adventure Oz the Great and Powerful has been curiously ramping up as of late, as we’ve recently seen two new posters and a batch of new images.  We knew that the one-sheets made up two-thirds of a triptych poster, and now that full banner has been revealed in addition to a couple more new images.  The pic is a prequel to the classic The Wizard of Oz, and centers on a small-time circus magician with dubious ethics (James Franco) who finds himself transported to Oz and drawn into a battle between the three witches Theodora (Mila Kunis), Evanora (Rachel Weisz) and Glinda (Michelle Williams).  The full banner and images show off even more of Raimi’s colorful world (though the photoshop on the poster is still a tad spotty), and I’m eager to see more footage from the film.  Hopefully a new trailer drops soon.Hit the jump to check out the poster and images.  The film also stars Zach Braff and Abigail Spencer.  Oz the Great and Powerful opens on March 8, 2013.Via Yahoo!

Here’s the official synopsis for Oz: The Great and Powerful:

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.
