She then went on to star in a number of movies in the 1970s, followed by numerous recurring roles in many prime-time TV series through the early 1980s, including her role of serious minded reporter Gretchen on Ladies' Man (1980–81) and as Beatrice Arthur's spoiled daughter-in-law Arlene on Amanda's (1983). Griffeth reunited with her former Ladies Man co-star Herb Edelman in an episode of The Golden Girls, playing Stan Zbornak's second wife, Chrissy.
