An MCU Fantastic 4 movie is in development. Little Women isn't really a fairy tale. A Dracula movie would be compared too much to Hotel Transylvania for Disney to want to do it. Moby Dick is not a fairy tale and it would turn a lot of people off just by the title. Huckleberry Finn is criticized a lot today so Disney might not wanna mess with it.
Building on the Red Riding Hood idea, I've been scripting a Disney-style adventure revolving around the Big Bad Wolf and his werewolf best friend. It's like a crossover between RRH, 3 Little Pigs, The Boy Who Cried Wolf, The Wolf in Sheep's Clothing, The Dog and the Wolf, and more!
