Book and movies Part 1 lists movies that successfully capture the literary plots that inspired their production. More often--as readers complain--a movie seems to use little more than a book's title.
And then there are those wonderful anomalies: movies which depart completely from their origins, yet are remarkable pieces of theater in their own right. Even better, sometimes such a movie will provide a new perspective on a novel's material. It captures the feel, the aura, of the original text even if it departs substantially from the original narrative arc.
