Final scene (spoiler) + script

Looking at the latest version it was interesting that Cimino increased the emphasis on the photo of Averill beside the woman from the graduation ceremony- presumably his wife- in his room in Bridges's saloon. However, looking at her re-appearance in the final scene on the boat I wondered if she is supposed to be physically paralysed. I'd taken her inertia and her request that Averill give her a cigarette and her passive acceptance of the cigarette as a deliberate contrast with Ella's activeness, but it is notable how very immobile the woman is. It makes very little difference to the film except as another instance of unrevealed back-story, but it's a strange occurrence.

In connexion with this, has any script of the film been published? Has anyone analysed plot variations and alterations as the film was planned and made?
