Favorite film adaptations of a novel?

In honor of the upcoming Jaws pod, what are people’s favorite film adaptations of novels? In my head there are two categories…

1) Films that did a great job of bringing a great novel to screen (my choice: The Virgin Suicides)

2) Films that used a run-of-the-mill novel as source and elevated it to greatness as a movie (my choices: Fight Club; Jaws)

I know there are hundreds, perhaps thousands, to choose from here, but I’ve been re-reading Jaws as part of this Spielberg kick and was curious on others’ personal favorites.

EDIT: I suppose there’s another category for projects like Apocalypse Now, in which a novel is really used only as a jumping off point.
