text: 1960s Kellerman made a number of television-series appearances. She was in an episode of the western Cheyenne, as well as a role as a waitress in the John Forsythe sitcom Bachelor Father. Struggling for parts in television and films, Kellerman acted on stage. She debuted in Henrik Ibsen's An Enemy of the People, followed by parts in a Pasadena Playhouse production of Leslie Stevens's The Marriage-Go-Round and Michael Shurtleff's Call Me by My Rightful Name (1962).
  Kellerman appeared in two episodes of The Outer Limits, first in 1963 in the episode "The Human Factor", and then in 1964 in the episode "The Bellero Shield" in which she played Judith Bellero, the manipulative and ruthless wife of Richard Bellero (played by Martin Landau). In between her two Outer Limits appearances, she was a guest in an episode of My Three Sons. A role as Holly Mitchell, perverted mistress of George Peppard's character in The Third Day (1965), followed. She played leading lady to David Niven in his television series The Rogues in 1965 for an episode titled "God Bless You, G. Carter Huntington" which revolved around her striking beauty to a large degree, and appeared in a 1965 Alfred Hitchcock Hour episode titled "Thou Still Unravished Bride".
