Cool? Not one of my own childhood movies, but I was always fond of how the Barbie movie franchise looked at any and all fairy tales and was like–hell yeah, we’re doing that somehow. Doesn’t matter if there aren’t any female characters traditionally, stick a heroine in that story.
Can’t really think of how a Princess/Prince&Pauper!AU would work because who looks enough like someone else to…
Oh, wait… Sasuke and Sai?
Maybe that’s Sai’s fairy tale origin in Tamed?
