So, the movies would be kind of like Enchanted. Any time it's the Otherworld, it would be live action, and in the Fairy Tale World, it would be classic hand drawn animation. The first four movies would be majority animation, but the last two would be primarily live action. Whenever they go into books in Beyond the Kingdoms and An Author's Odyssey, the animation would become more cartoon like depending on the story. For example, The Wizard of Oz and Peter Pan would be closer to the animation used throughout the films, while Alice in Wonderland and most of Conner's short stories would be more like the original Mickey cartoons, very exaggerated. I don't have everyone casted, so you may have to use your imagination for some characters.
