Movies in which they changed the ending from the book.

The Fountainhead. I loved the book but the film absolutely sucked.
Ahh, Dominique Francon. I couldn't agree more Jag.
Apparently they changed the ending of the The Last Detail so that Buddusky doesn't die, although I haven't read the book (and I'm not sure anyone has). That's an awesome movie. Maybe Nicholson's best work.
most books are completely re-written for the screen. Elmer Gantry is a perfect example (the movie is just awful with the exception of Lancaster's performance). The book is great btw.

York was never sacked by the way…
The best re-write is the Scarlet Letter. I always found the book tedious, but man, if you add in a happy ending AND an indian attack, you've sold me. And that slave bathroom candle masturbation scene? GOLD!
Angelas Ashes
Not a book, book per se but a graphic novel, "Ghostworld" took what was maybe a minute fraction of the story (maybe two to four pages) and turned it into a whole plot thread. It does boast having America's sweetheart Scarlett Johansson in a she's not quite America's sweetheart co-star role.
Also Steve Buschemi whom always seems to make a movie that much more watchable. So eh.
