McKellar wrote the script so audiences would see the world through the eyes of the protagonist, the doctor's wife. He sought to have them question the humanity of how she observes but does not act in various situations, including a rape scene. He consulted Saramago about why the wife took so long to act. McKellar noted, "He said she became aware of the responsibility that comes with seeing gradually, first to herself, then to her husband, then to her small family, then her ward, and finally to the world where she has to create a new civilization."
Wow this does not come through to me at all
