Dream Script

I had a surreal dream this morning. I was watching a rough cut of a movie with my favorite actor and we were going to edit the film. He starred in the film as well. (Pretty sure this doesn't happen stretched out on the carpet in front of an old tv from the 80's with knobs and a VHS machine, but hey, dream rules). We talked about one of the scenes, which was dialogue heavy and a bit awkward.

GirlZoot showed up (but had always been there, dream rules again) with the script and I looked at the opening sequence of images, which had explanations in the script. The entire opening sequence suddenly made sense and I wasn't sure if that was a film thing or a me thing. I suddenly had a burning question. "Is there a final version of the script that matches what the final edited version of the film is?" Never got an answer. I was thinking there's always the deleted or extended scenes, they're part of the original script. Do they stay part of the script or are they marked or removed from the 'final' version? It's different from books, where the final version is it; a screenplay isn't necessarily the last word, editing and at times ad lib play such a big role. (Thank you GirlZoot and Shaych for your film commune / school rubbing off on me).

Around this time, his girlfriend showed up (but had always been there) and the four of us began discussing the film and current events and such. She had an accent, French I think, and was very sweet. They started horsing around together, doing this one leg wrapping thing that I'm pretty sure is physically impossible. They were so cute and madly happy together, my tiny pang of jealousy seemed petty. There was a bit more talking about the script but no more movie watching, just hanging out and enjoying it.

So can anyone tell me, is there a final version of the script that matches the edited film? Is it always that way? Does it depend on the screenwriter? My curiosity is piqued.
