Query: A must-have for Brokeback fans

"Story to Screenplay" is an incredible compilation of the Proulx short story, the amazing Osanna/McMurtry screenplay, and photos and comments from writers and director. It shows how painstakingly faithful the screenplay is to the story and also will 'fill in the blanks' for any lines from the movie that may have been hard to hear. And, despite the screenplay's format, reading it is as gut-wrenching and heartbreaking as reading the short story and seeing the film. The comments from Prolux, Osanna, McMurtry and Eng show how this film was a geniuine labor of love from all of its participants.
