Snow White is seen briefly in Shrek the Third during a gathering of princesses. The Magic Mirror features prominently in several of the features, offering counseling (though forced) to Lord Farquaad in the first film. Dwarves are seen at various times.
Snow White by the Brothers Grimm freely translated from the German by Paul Heins with Pictures drawn by Trina Schart Hyman. Little Brown, 1974.
Snow White by the Brothers Grimm, illustrated by Quentin Greban. NorthSouth, 2009.
The text sticks pretty close to the original story, with the evil stepmother being forced to don the red-hot iron shoes at Snow White's wedding. Greban's watercolor illustrations are delicate and appealing.
