The first poster for next year’s animated Dorothy of Oz has just been revealed over at Yahoo! Movies. The film–one of several Wizard of Oz spin-offs currently in the works–seems very much inspired by Tim Burton’s recent Alice in Wonderland film, with the story involving Dorothy being called back to the land of Oz to save it from an evil jester who wants to turn everyone in the kingdom into his puppets. As is often the case with independently made animated features, the producers have managed to get an all-star cast attached to the project, including Martin Short, Kelsey Grammer, Hugh Dancy and Patrick Stewart. Coming from Summertime Entertainment, the movie is aiming for a summer 2012 release.
