I heard that the makers of Harry Potter are making a movie about the stuffed bear Paddington who like Marmalade like Pooh likes honey. Sounds like attempt to cash on the pooh crowd. I find it weird that Disney owns Marvel and yet all the superhero rides are in Universal and Six Flags.
Universal had a pre-existing deal with Marvel that gave them the exclusive them park rights to the major Marvel characters east of the Mississippi, do there is not much Disney can do with Marvel at WDW. Six flags uses the DC superheros, not Marvel.
