(Unless its a Tom Clancy novel, where throwing out 99% of the text leaves a perfectly fine movie.)
_Gone With the Wind_ and _Doctor Zhivago_ also made pretty darn good movies and they were doorstops of books. Of course, they had to cut out one of Scarlett O'Hara's *children* from the movie (but she fell out pretty darn seamlessly!)
