“Scarecrows and magic and other fatal fears do not bring people closer together. There is no magic substitute for soft caring and hard work, for self-respect and mutual love. If we can learn this from the mistake these frightened men made, then their mistake will not have been merely grotesque, it would at least have been a lesson. A lesson, at last, to be learned.”
It was an episode of the Outer Limits TV series in 1963-64 starring Robert Culp.
