We all know the Disney version. Two little mice go to rescue a little girl kidnapped by Medusa (or whatever her name is LOL) who's currently residing in a swamp somewhere. Other country-bumpkin animals help along the way as well as the albatross who takes them to and from their locations.
Well, the only way it resembles the real story is the fact that there are two little mice named Bernard and Bianca. The REAL story is very interesting what with a black castle, a Norwegian sea mouse, a fat cat and the rescue of a writer.
I am now in horror at what they might do to one of my favorites, The Tale of Despereaux, when it becomes a movie.
Please read the real version of the Rescuers by Margery Sharp. It's worth it.
