Got the part of J. R. Ewing's young trophy wife, Cally Harper Ewing, on
Dallas (1978), was she read for the casting director, who was already impressed with it. Her character was only supposed to be a guest-star, for 7 episodes, however, the producers, especially
Larry Hagman really liked her the best, and came back to play her role, for the last 3 seasons, replacing veteran actress,
Linda Gray.
