The creation of the island, or the impression of the island, as it changes in the mind of the character also came in to play. . . there was another very important collaborator, Rob Legato, on special visual effects. And then ultimately there's Thelma Schoonmaker, who keeps me focused during the editing of the picture.
Such is luck! And such the treatment which honest, good perservance gets so often at the hands of unfair and malicious Nature!
