I don't know if this has been discussed before, but there were a few differences in the story and the book that I found interesting. The smallest were the name changes - Francine to Jennifer, Bill to Monroe. Pretty insignificant. One thing that struck me, though, was the stronger sexual current in the story as it progressed. During one of their "fishing" forays, Jack opens a bottle of whiskey, takes a slug, and says something like "That's one of two things I need right about now." I don't have the book in front of me at this moment, but more significantly, on their last trip together, there's a scene where they're talking about their families, and as they do so they're touching each other - Jack puts his hands between Ennis's legs, Ennis unbuttons Jack's shirt - and ultimately they "roll into the dirt" at which point Proulx writes about the "brilliant charge" of their infrequent couplings being accompanied by the spectre of time flying by. The time passage is achieved by the river rushing past, in several of these scenes, but I'm wondering if the filmmakers' choice not to emphasize the purely sexual aspect of their relationship after the hotel scene (other than a couple of references by Jack)was an artistic one, or if they (the writers, Ang Lee) felt they'd done that, and that anything further would be superluous and/or make the film less palatable for wider audiences. Has this come up in any interviews or any other material out there I might not have read?
