I think the line I noticed first off that was missing from the film was Jack's line in the SS motel scene: "Come on Ennis, you just shot my airplane out a the sky - give me somethin a go on. This ain't no little thing that's happenin here."
I guess having moved a lot of the dialogue of the motel scene to the campfire scene in the film, which of course happened a lot later, that line wouldn't have fitted there, but there's just something about that line in the original motel scene that for me shows right from the motel scene that Jack's well and truly got the dream of the 'sweet life' right from the start. The other thing about the motel scene in the SS, of which that line's the final line after the 'what happens now' part, is that in the SS it's clear from that exchange how they come to be camping straight after - with the film version you jump from the motel to the apartment above the laundromat to the jumping from the cliff into the lake. If you're paying attention (or of course if you've seen the film a zillion times before
) obviously you know/can figure out what's going on without the momentary "huh? where did that come from?" feeling.
The other thing I feel with the SS compared with the film version is though that whole chunk of dialogue is shifted to the campfire scene where they're both fully clothed, as Fiona says, the reunion/motel scene in the SS shows a much more tender Ennis, and is a lot more intimate. In the film version, again, unless you're watching closely and reading the 'sub-plot' it's easy to see that scene again as 'just sex.'
I do have a theory on that though, which Fiona's comment about the special edition DVD for those with "more open minds" reminded me of. Just about everyone can relate to sex, even if they don't understand two men having sex; everyone knows it happens. It takes a lot bigger leap of imagination though to understand two men loving each other. Maybe it was partly that there was a feeling that the public would accept the 'just sex' version better, and yet the open-minded would see the sub-plot as well. For example, the "couldn't get here fast enough, red lined it all the way" line, you can read a lot more into than just the words, and one of the hallmarks of the film all the way through is it's subtlety. How it's shown in the film you
could read that scene either way. With the SS it's much clearer. I may be way off base there, but that's just may take on one of the reasons the dialogue from the motel scene got moved to the campfire in the film.
Hmmmm...well considering it's a 'story only' topic, I've managed to go somewhat off-topic!
I'll ponder the SS motel scene some more later...
