Favorite films adapted from novels

Technically this is adapted from a "novella"

I've never made any secret about my proclivity for non-fiction rather than fiction reading, so I'm woefully ill-equipped to offer much comment on the topic.

In addition to Double Indemnity (about which you and I have had much discussion of both novella and film), Laura is among my anytime/anywhere films. I'm only just now getting around to Vera Caspary's novel and, although it's a relatively short read (under 200 pages), I'm finding it a bit of a slog and reading only in dribs and drabs. Waldo on the page is garrulous to a rather tiresome fault, and lacks the incisive and lacerating brevity that made his screen counterpart so compelling. But I shall press on. 

Of the others cited upthread, I've read only The Caine Mutiny. I've always loved the film and have seen a televised version of the B'way play directed by Robert Altman, which featured Brad Davis as Queeg and seemed much more in line with Wouk's depiction of the weaselly commander than Bogart's battle-weary one (I hasten to add that I find it to be his very best work; the film reinvented the character, and Bogie not only ran with it, he spiked it at the goalposts). 

But I love the novel as well, and still yearn for a full screen treatment of the entire story, which cries out for a three-part HBO-style mini-series. In its construction, it's almost as though Wouk was imagining the form over twenty years before it was invented. 

GONE GIRL, adapted for the screen by the book's author Gillian Flynn and directed by David Fincher.

Two more favorites that are adaptations from "novellas"... both by Stephen King and both from "Different Seasons"

I like the film because I LOVE the novel. Probably, no film could ever measure up to Marquez's great novels.

Haven't seen or read this one, but I love the cast and the idea of the story.  Will keep an eye out for it.  Thanks for the recommendation.
