What's the name of the movie that was made based upon the book "Fairest" by Gail Levine? It's juvenile literature.

Have you actually seen a movie based off Fairest? I don't know that there is one. It seems as though the book has strong similarities with Snow White - there are many movies based off that story.

Are you perhaps thinking of Ella Enchanted, a different book by the same author, which was made into a movie? Ella Enchanted (2004) - IMDb

Both books are set in the same world.
