During an August 3, 1970 interview on "The Dick Cavett Show", Kidder stated that she was ambivalent toward having a film career, and was considering working as a film editor in the future. At this time, she had become an acquaintance of director Robert Altman, and served as an apprentice assisting him in editing "Brewster McCloud" (1970). She subsequently appeared in "Such Dust As Dreams Are Made On", the first pilot for "Harry O" which aired in March 1973. She was a guest star in a 1972 episode of the George Peppard detective series "Banacek".
