Both the story and screenplay will move you to tears, make you feel like someone's pulling your guts out hand over hand a yard at a time, as Annie Proulx writes of Ennis. They will also make you treasure love more. The screenplay is one of the best I've read -- a terrific read and a faithful adaptation and expansion. If you're interested in delving deeper into the lives and loves of these characters and the starkly beautiful honesty of this world, buy this book. The screenplay and the essays by Annie Proulx and the two screenwriters, Larry McMurtry and Diana Ossana, offer a good deal of insight and color, from the germ of an idea for a short story to final film. Fascinating and powerful.
