This is the movie Mike was watching in his hotel room with his wife and her sisters.
It is based on the true story of Shirl Jennings who was diagnosed with retinitis pigmentosa, a progressive, untreatable disease of the retina that causes blindness at age 7. At the age of 51 he had a surgery that removed his scarred cataracts and restored his vision. But 1 year later in February 1992, Jennings contracted pneumonia, which led to respiratory failure that deprived his brain of oxygen. After recovering, while he could still see some colors and movement, his sight virtually vanished.
The most interesting thing about this film is that it was written by Oliver Sacks, a world famous neurologist and author of one of the “Supplemental Readings.”
