This was a great script from the prolific Larry Cohen, who wrote episodes for "Columbo," "Arrest and Trial" (a forerunner of "Law and Order") and episodes for Kraft Suspense Theater and "The Defenders." He has also written feature films.
I'd love to see this film again - I wish it would come out on video. It stars Richard Boone as a newly-blinded actor and Suzanne Pleshette as his teacher. Though the Boone character puts on a big show for Pleshette of refusing to accept his blindness, he coldly and calculatedly trains himself to act as a seeing man so that, in disguise, he can get rid of his wife and her lover.
It's a suspenseful story, a fascinating character-study and all around great entertainment. For some reason, this kind of TV movie fare has gone out of style and been replaced by women at risk films, rather slow-moving versions of Robin Cook and Mary Higgins Clark novels and the like. But we mystery buffs old enough to remember the '70s remember - with nostalgia - this kind of film.
