An excerpt from Harlan Ellison's screenplay adaptation of "I, Robot" has this to say about Dr. Calvin; ""She is a small woman, but there is a towering strength in her face. Tensile strength, that speaks to endurance, to maintaining in the imperfect world. Her mouth is thin, and her face pale. Grace lives in her features, and intelligence; but she is not an attractive woman. She is not one of those women who in later years it can be said of them, "She must have been a beauty when she was younger". Susan Calvin was always plain. And clearly, always a powerful personality"".
