Actress Lynda Day George was quite busy on TV in guest-starring roles throughout the 1960s. Before she officially changed her professional name from "Day" to "Day George" -- to acknowledge her marriage to actor Christopher George -- Day George was a regular on The Silent Force, a 1970 Mission: Impossible clone. Ironically, one year later she was cast on the real Mission: Impossible as undercover operative Casey, a role she retained until the series' cancellation in 1973. While she has appeared in the occasional theatrical film, most of Day George's best work could be seen in such small-screen miniseries as Rich Man, Poor Man, Once an Eagle, and Roots. In the early '80s, Lynda Day George began turning down network roles to devote her energies to religious television, remaining active in this field long after the death of her husband in 1983.
